How can I get the Google cache age of any URL or web page?
提问by Tokendra Kumar Sahu
In my project I need the Google cache age to be added as important information. I tried to search sources for the Google cache age, that is, the number of days since Google last re-indexed the page listed.
在我的项目中，我需要将 Google 缓存年龄添加为重要信息。我尝试搜索 Google 缓存年龄的来源，即自 Google 上次重新索引列出的页面以来的天数。

Use the URL
使用网址
https://webcache.googleusercontent.com/search?q=cache:<your url without "http://">
Example:
例子：
https://webcache.googleusercontent.com/search?q=cache:stackoverflow.com
https://webcache.googleusercontent.com/search?q=cache:stackoverflow.com
It contains a header like this:
它包含一个像这样的标题：
This is Google's cache of https://stackoverflow.com/. It is a snapshot of the page as it appeared on 21 Aug 2012 11:33:38 GMT. The current page could have changed in the meantime. Learn more
Tip: To quickly find your search term on this page, press Ctrl+For ?+F(Mac) and use the find bar.
这是谷歌的https://stackoverflow.com/缓存。这是 2012 年 8 月 21 日格林威治标准时间 11:33:38 出现的页面快照。在此期间，当前页面可能已更改。了解更多

you can Use CachedPageswebsite
您可以使用CachedPages网站
Cached pages are usually saved and stored by large companies with powerful web servers. Since such servers are usually very fast, a cached page can often be accessed faster than the live page itself:
缓存页面通常由拥有强大网络服务器的大公司保存和存储。由于此类服务器通常非常快，因此通常可以比实时页面本身更快地访问缓存页面：
- Google usually keeps a recent copy of the page (1 to 15 days old).
- Coral also keeps a recent copy, although it's usually not as recent as Google.
- Through Archive.org, you can access several copies of a web page saved throughout the years.
- Google 通常会保留该页面的最新副本（1 到 15 天前）。
- Coral 还保留了一份最近的副本，尽管它通常不像 Google 那样新。
- 通过 Archive.org，您可以访问多年来保存的网页的多个副本。

its too simple, you can just type "cache:" before the URL of the page. for example
if you want to check the last webcache of this page simply type on URL bar cache:http://stackoverflow.com/questions/4560400/how-can-i-get-the-google-cache-age-of-any-url-or-web-page
它太简单了，你可以在页面的 URL 前输入“缓存：”。例如，如果您想检查此页面的最后一个网络缓存，只需在 URL 栏上输入cache:http://stackoverflow.com/questions/4560400/how-can-i-get-the-google-cache-age-of-any-url-or-web-page
this will show you the last webcache of the page.see here:
这将显示页面的最后一个网络缓存。请参见此处：
But remember, the caching of a webpage will only show if the page is already indexed on search engine(Google). for this you need to check the meta robot tag of that page.
但请记住，仅当页面已在搜索引擎（Google）上编入索引时，网页的缓存才会显示。为此，您需要检查该页面的元机器人标签。
