It is impossible to guess when a page with information of interest will be deleted. At any time, a resource can be blocked or transferred to a new domain. This makes it difficult to find content that the user has previously viewed. We have to study the distribution results in Google and Yandex again. However, there is no guarantee that the computer owner will find what he was looking for.
What is cache and how does it work
The function is built into almost all modern programs. The browser stores the information the user views to reduce the time it takes to reload content. All files are stored in the temporary clipboard folder, which is most often located on drive C. This includes: texts, html files with layout data and pictures. The number of saved materials is limited only by the amount of built-in memory of the computer and the settings of the individual browser.
Cash is necessary to speed up the system. Every time the PC owner opens a link, the browser saves all published information to the selected address. When you request the same address again, the browser finds the required file in the temporary data folder and downloads it, correcting the changed information. This reduces traffic consumption and avoids overloading the line. Each duplicate is stored in the device’s memory, so the user can even download content that is not available on the Internet.
Search engines are also capable of creating copies in cash. If the site owner deleted it or the resource was blocked, the user will still be able to view the page that interests him. It will not be possible to see the latest changes or make any edits. Users will also not be able to:
- leave comments;
- evaluate records;
- publish new materials.
How to find a site's cache in Google
To open a copy in a search engine, you must enter the name of the site and the article of interest in the request. Select the appropriate option from the results found. To the right of the address is an arrow pointing down. By clicking on it, the user opens additional options. To download a file from Google cache, you need to click on the “Saved copy” button. The browser opens a new tab in which the page of interest will be displayed. You can open the resource directly, without using search results: to do this, enter the request cash.link, where the word “link” is the domain of the required service.
Interesting fact!
The search engine caches all links daily, so by downloading a copy, the computer owner will see the latest available version of the site.
Searching for a copy of a page in Yandex
The mechanics of cash on the Russian resource are no different from the Google search engine. To open the copy of the site you are interested in, you need to make a request for its domain. Next to the address there is an arrow from which a menu of advanced options drops out. To load a duplicate resource from the cache, select the “Saved copy” option. In the tab that opens, Yandex always indicates the download date of the displayed version of the site.
How to remove a site from the cache
To speed up page indexing by search engines, resource owners remove old versions from the cache. Thus, Yandex and Google do not bypass links that are already registered in their system. Both systems periodically update the data, but this is done by a robot. Due to this specificity, updating information takes longer than with the intervention of the site owner.
To remove a page from Google cache, you must:
- Log in to the Webmaster service.
- Go to the “Delete URL” menu section.
- Click on the “Temporarily hide” button so that the pages no longer appear in search results.
- Enter the link address.
- Click the “Continue” button.
- Select the required type of deletion, in this case the second item.
- Confirm the request.
- Wait for the application to move from “Pending” to “Completed” status.
Attention!
The Yandex search engine also supports clearing the page cache, but to do this you will have to completely remove the link from the catalog. This resets all statistics and indexes.
A blocked site is not a death sentence. Yandex and Google services constantly create a cache of all resources, so users will be able to access them even after deleting content from the servers. This does not require additional software. You can open a copy in just 2 clicks. At the same time, it will correspond to the latest current version of the site. Pages from the cache can save web programmers if code changes have brought down the entire interface, and they can’t remember what it should look like.
Services and tricks with which you can find EVERYTHING.
Why is this needed: Did you briefly read the article in the morning and decided to take a closer look in the evening, but it’s not on the website? A few years ago you visited a useful site, today you remembered it, but there’s nothing left on the same domain? This has happened to each of us. But there is a way out.
Everything that goes on the Internet is stored there forever. If some information is posted on the Internet for at least a couple of days, there is a high probability that it has become the property of the collective mind. And you will be able to reach her.
Let's talk about simple and publicly available ways to find sites and pages that have been deleted for some reason.
1. Google cache that remembers everything
Google specifically stores the text of all web pages so that people can view them if the site is unavailable. To view the version of the page from the Google cache, type in the address bar:
http://webcache.googleusercontent.com/search?q=cache:http://www.iphones.ru/
Where http://www.iphones.ru/ must be replaced with the address of the site you are looking for.
2. Web-archive, which contains the entire history of the Internet
6. Archive.is, for your own cache
If you need to save some web page, you can do this on archive.is without registration and SMS. There is also a global search for all versions of pages ever saved by users of the service. There are even several saved copies of iPhones.ru.
7. Caches of other search engines, you never know
If Google, Baidu and Yandex did not manage to save anything sensible, but a copy of the page is really needed, then we go to seacrhenginelist.com, go through the search engines and hope for the best (so that some bot visits the site at the right time).
8. Browser cache when all else fails
You can’t view the entire page this way, but images and scripts from some sites are stored on your computer for a certain period of time. They can be used to search for information. For example, using a picture from the instructions, you can find a similar one on another site. Briefly about the approach to viewing cache files in different browsers:
Safari
Looking for files in a folder ~/Library/Caches/Safari.
Google Chrome
In the address bar we type chrome://cache
Opera
In the address bar we type opera://cache
Mozilla Firefox
Type in the address bar about:cache and find on it the path to the directory with the cache files.
What to do if nothing helps at all
If none of the methods yielded results, and you desperately need to find the deleted page, then all that remains is to contact the site owner and shake out the treasured information from him. To begin with, you can get through the contacts associated with the site on
Modern browsers are designed in such a way that almost all the information that the user requests from the Internet is saved by the browser on the local hard drive of your computer. This is done in order not to download the same files every time the user requests, that is, in order to save traffic, as well as speed up the browser - using a cache (this process is called caching) allows you to download pages to which the user has already accessed it much faster, since most of the files that make up the web page have already been downloaded to the computer. When you access the page again, the browser only needs to check whether any elements have changed since the last time you accessed it, and reload only the changed elements. Such elements can be anything that makes up website pages - images, text, video, sound.
Thus, the browser cache is a certain area on the hard drive in which files downloaded from the network when viewing web pages are stored. It is necessary to periodically clean the Internet conductor. Below we will figure out how to clear your browser cache.
It usually has a limited capacity, since old unused files are constantly replaced by new ones as the user works.
By the way, the concept of a cache is quite broad, and this principle is used not only in browsers, but in this article we consider it in relation only to them.
Why do you need a cache?
So, how can a cache be useful? If all the files that a user has ever viewed are saved in the browser, then it may be that the user may need a particular file. For example, after listening to a piece of music or watching a movie online once, we may want to save this file for repeated use. I do this very often with music - I listen to music online, and I can “get” the songs I like from the browser cache and save them in my music library for repeated listening. The same can be done with videos.
Video: What is a cache, what is it for and how to clear the browser cache?
Another interesting use of the cache is to speed up the loading of web pages. Since most small files are stored on your computer's hard drive, re-accessing those files in the cache still takes some time - although much faster than downloading from the network. But you can still speed up the cache. To do this, you need to place the browser cache in the computer's RAM. Reading from RAM occurs almost instantly, which allows you to speed up the reloading of web pages by 2-3 times in contrast to normal speed. I will tell you how to do this in another article.
In the meantime, let's see how you can get files from the browser cache. Cached files have inconvenient names, which, in the absence of certain knowledge, creates difficulties in finding the desired file.
Where is the cache located?
The browser cache is located in the browsers' working folders. A cache is nothing more than a regular folder containing these same files; as a rule, it is called “cache”. In the Linux operating system, the browsers' working folders are located in the user's home directory. The Opera cache can be found at ~/.opera/cache/. For Firefox it is located in .mozilla/firefox/[random profile number].default/Cache/
In Windows XP, the Opera cache is located in C:\Documents and Settings\[username]\Local Settings\Application Data\Opera\Opera [version]\cache
The Firefox cache is located at a similar address: C:\Documents and Settings\[username]\Local Settings\Application Data\Mozilla\Firefox\Profiles\[random profile number].default\Cache.
Finding files in the cache
That's sorted out. But if you go into these folders, you will see a lot of files (sometimes several thousand!) with meaningless names that mean nothing to the user, and without extensions. If you are a Linux user, then the file manager will recognize most files and display the file type and corresponding icons, since Linux recognizes files regardless of their extension. But in Windows there is no such luxury - in order for the shell and file manager to recognize files, extensions are needed (usually three-letter combinations separated by a dot after the file name - .exe, .mp3, .avi, .doc, .pdf, etc. etc).
Fortunately, you can identify files and find the one you need not only by name. Any files have attributes such as size and date of saving. Thus, we can almost always tear out the file we need from the browser cache immediately after watching or listening. All you need to do is set the file manager settings to display the size of files and the date they were modified. In Windows, for this you need to set the display type to “Table”. Now you need to sort the files in the cache by date or size.
Searching for video and audio files in the cache
Video and audio files are usually several megabytes in size, so they will be clearly visible if you look in the "Size" column, since all other files are several kilobytes or even bytes in size. You can distinguish the files you just watched or listened to by the date and time they were changed. All you have to do to recognize a file is add the appropriate extension to its name - “.mp3” if it’s music or “.flv” if it’s a video. With all these things in mind, it's quite easy to pull out the last file you listened to or watched online. You can copy the desired file to any convenient location and give it any name convenient for you.
Opera cache
But that is not all. Both Opera and Firefox have their own tools for viewing caches, but I find that using your operating system's native file manager is much more convenient. In order to view the cache in Opera, you need to type opera:cache in the address bar and the contents of the cache will appear in front of you in an easy-to-view form. In addition, in the new version of opera 10.50, elements have been added to this tool for easy recognition and search of the required files, both by size and type. Moreover, the web address of the file source is also displayed.
Firefox cache
Firefox also has a similar tool, but there you can only view the contents of the cache. It displays the file size, save date and source, as well as some information about the file that is useless for the average user. In order to view the cache in Mozilla Firefox, you need to type about:cache in the address bar.
Clearing cache in Mozilla Filrefox
Or like this, you can clearly see how to clear the cache in Firefox:
How to clear cache in Google Chrome browser
Many years have passed since this article was written. A lot has changed in the world of software - information technology is developing very rapidly. At that time, the Google Chrome browser did not yet exist, or it had just appeared. Now this is practically the most common browser, along with Firefox, while Internet Explorer and Opera have practically disappeared from users’ computers (by the way, it was replaced by an interesting one), and many browsers have appeared based on Crhomium - Yandex.Browser, Amigo and others. To clear the cache in Google Chrome, you need to go to the menu, select “Settings”, then expand them, and find the “Clear browsing data” item there. Please note that here you can select the period for which you want to erase data.
Well, actually, now you can use this convenient thing.
Greetings!
In the process of opening and viewing sites, the browser automatically saves files that are elements of the pages being viewed. These can be graphic elements, audio and video, style sheets, js files, html files and so on.
All these files are stored in the browser cache, and are subsequently used to speed up the formation and display of website pages. The principle of operation of the cache is very simple - if one or another element of the page of the site being opened is saved locally, then the browser uses it when generating the page, and does not request it again from the Internet. Naturally, retrieving a file from the cache is disproportionately faster than if it were downloaded from the network.
Knowing this circumstance, users resort to extracting these saved files. For example, this may be needed to find out which sites were viewed and what content was directly displayed there. This can be determined by the saved graphic elements (pictures, photographs) from the sites you are viewing that have been saved in the browser cache.
The only problem is that in the Google Chrome browser and those based on its “base” (Yandex Browser, Opera, and so on), the cache files cannot be accessed directly. More precisely, if you open the folder with the cache, you will not find directly saved files, but you will only see files with serial numbers. But we are solving the issue of accessing the cache in the browser, which will be discussed in this material.
Instructions for viewing and extracting (copying, saving) cache files in Google Chrome, Opera, Yandex browser, etc.
To solve this problem we will use a miniature utility called "ChromeCacheView", which works without installation and has support for the Russian interface language (the language file is downloaded separately and copied to the folder where the utility itself is located).
Using such a simple solution, you can easily view and copy files from the cache of the Google Chrome browser, as well as other browsers based on Chromium code.
The word cache can be heard quite often in various areas of IT, but today we will deal with page cache site. The term itself means that search engines save copies of pages from a certain number, usually from the robot’s last visit to the site. You can find and use a copy (cache) of the page at any time for your needs.
It's pretty good that search engines save pages on their servers for a while and give us a chance to take advantage of this. A lot of resources and money are allocated to storing cached pages, but they pay for their help, since we still need to go to their search engines.
Why do we need a cache (copies) of pages?
There are different situations when working with websites.
As always, you have a lot of work, but little time and not enough attention for everything. There are times when work is being done on the site, suppose a design change or minor edits to the template or text. And at one point you realize that you made a mistake somewhere and the text disappeared or part of the site design disappeared. Well, this happens and everyone has probably dealt with this.
At the moment, you don’t have backups, and you also don’t remember what everything looked like initially. In this case, a copy of the page, which can be found in the cache of both Yandex and Google, can help, see how it was originally and correct it.
Or second case, You have changed the text a little in order to improve it and want to see whether the page on which you made the changes has been updated or not. You can check using a page that is in the cache; to do this, look for this page and look at the result.
There is also a situation when the site is not accessible, for one reason or another, and you need to go to it. In this case, a copy of the page can help, which can be found in the following ways.
In general, I think it has become clear that using a page cache is necessary and useful.
How to find a page in Google, Yandex cache
First, let's look at how to search in the Google search engine.
Method number 1.
You go to the search engine page and enter the address of the page you want to find and view a copy of. I'll take our site as an example:
We enter the name of the page or site in the search bar, press “Enter” and see where the page you were looking for is displayed. We look at the snippet and there is a URL (address) to the right of it with a small down arrow, click on it and we will see the “Saved copy” item. Click on it and we will be transferred to a copy of the page from a certain date.
Method number 2.
The method can be called semi-automatic, since you need to copy the address below and substitute the domain of your site instead of site.ru. As a result, you will receive the same copy of the page.
http://webcache.googleusercontent.com/search?q=cache:site.ru
Method No. 3.
You can view the cache using browser plugins or online services. I use for these purposes.
Here you can see when the robot last visited the resource, and accordingly, a copy of the page will be for this date.
Now let's look at how to search for a cache in the Yandex search engine.
Method number 1.
The method is the same as for the Google system. We go to the search engine page and enter the address of the page you want to find and view a copy. I’ll take our website as an example again and write it down:
We enter the name of the page or site in the search bar, press “Enter” and see the search results, where the page you were looking for is displayed. We look at the snippet and there is a small downward arrow to the right of it, click on it and the “Saved copy” item appears. Click on it and we will be transferred to a copy of the page from a certain date.
Method number 2.
We use additional browser plugins. Read a little higher, everything is the same as for Google.
If the page is not in , then there is a high probability that it is not in the cache. If the page was previously in the index, then it may be preserved in it.
How to clear cache in Yandex, Google
It may be necessary to remove a page from the Yandex or Google cache or even hide a page that was previously indexed and cached from prying eyes. To do this, you need to wait until the search engine itself discards this page naturally if you have previously deleted it. You can prevent the page from being indexed in a file or use the tag:
Just be careful with the tag, do not put it in the general site template, because it will prohibit caching of the entire site. For these purposes, it is best to use additional plugins or programmers who have previously done such work.
Now let's see how you can clear the cache (clear, delete page) using the Google and Yandex search engines.
Clear page cache in Google
The Google search engine approached this issue from the right side and created such a tool as “ Remove URLs» in Webmaster Tools. To use it you need to go to webmaster tools at:
www.google.com/webmasters/
Clear page cache in Google Webmaster In order to clear the cache or delete the entire page (or you can also immediately delete and clear the cache together), you need to click on the “ Temporarily hide" and enter the url address of the page that needs to be cleared and click the button " Continue«.
Now in this window, when you click on the list “ Request type"You can see several ways to delete and clear both a page from the Google index and clear the cache.
- If you need to completely delete the page and cache, then use the first method.
- If you just need to clean it, then use the second method. As a rule, for our example we need to use it. The page remains in the index, but the cache is deleted and the next time the robot arrives, it will appear there again.
- If you need to temporarily hide, then use the third method. It is used when pages do not have time to fill with quality content. In this case, it would be better to hide it for a while.
As soon as you choose one of the methods, in this case 2nd, click on the button “ Send request«.
After clicking, we get a page where you can see that this page has been added for deletion from the cache and is in the status “ Expectation". Now all that remains is to wait. Typically, this procedure takes from several minutes to several hours.
If you have entered the page incorrectly and want to cancel, you can click on the “ Cancel«.
After you go to the Remove URLs tool after some time, you will be able to see the status as Completed. This means that Google robot visited the page and cleared its history.
Clear (delete) page in Yandex
The Yandex search engine has a similar tool in its webmaster tools, but there is one “BUT” here. There is no cache clearing as such; you can completely delete a page from the PS index and at the same time its entire history will be deleted.
In order to use this tool, you need to go to Yandex webmaster using the link:
webmaster.yandex.ua/delurl.xml
and enter the required URL in the line.
The search engine will exclude this address after some time “AP”. As a rule, Yandex takes a couple of seconds to do this, so you will need to wait.
