有时您可能希望从搜索引擎的角度查看页面。在其他时候，人们可能会离线并想要查看某些网站。在其他情况下，人们可能希望查看他们或某人的网页的旧版本。所有这些都要求您在搜索引擎缓存中查看旧的、存档的或缓存的网页。这篇文章告诉您如何查看缓存网页的(view a cached web page)不同方法。
(View Cached)使用Internet(Internet)档案查看缓存网页
在我们了解如何做之前，让我们看看为什么搜索引擎会缓存网页。
为什么搜索引擎会缓存网页？
搜索引擎缓存网页的主要原因有两个。首先是管理进出其服务器的流量。尽管他们在大量服务器上缓存和保存不同的屏幕截图，但有时对某个页面的需求很高。当搜索引擎必须迎合超出其处理能力的流量时，它会求助于缓存的网页。在这种情况下，结果中显示的网站描述可能不属于最后一个索引页面。
第二个目的是在用户无法访问时为用户提供网站。导致网站无法访问的原因包括： 1)网站(Website)已关闭；2) 用户没有连接；3）网站不存在了。
除了搜索引擎，一些网站也会定期创建Internet档案。(Internet)他们试图通过索引它们并拍摄它们的快照来存储尽可能多的网站。这是为了让人们可以研究一个网站——例如两年前一个页面的外观。这也使用户能够查看现在已更改域的网站。
直接在浏览器中查看缓存的网页
所有主流搜索引擎都允许您在搜索框中使用命令来过滤搜索结果。例如，如果您想查看网站是否包含特定关键字的内容，您可以输入：
keyword site:websiteURL
或者您可以在浏览器中输入以下地址直接查看缓存页面：
http://webcache.googleusercontent.com/search?q=cache:<URL>
同样，要查看网站的最新缓存网页，请使用缓存命令，如下所示：
Cache:URL
例如，如果您想查看TheWindowsClub.com(TheWindowsClub.com)的缓存网页，请在浏览器的地址栏中键入cache:thewindowsclub.com。
请记住(Remember)，您不应在命令中输入URL的(URL)HTTP部分。并非所有搜索引擎都会处理它。但是，您可以使用 www 和子域。例如，cache:news.thewindowsclub.com将显示Windows Club新闻子域的缓存页面。
此外，请勿在(NOT)完整的冒号之前或之后放置空格。如果这样做，它将假定CACHE是一个关键字。
在浏览器中使用搜索结果
例如，当您使用Google进行搜索时，您会看到与显示的(Google)URL(URLs)相对的倒三角形。当您单击三角形时，您将看到一个选项，该选项会将您带到缓存页面，而不是直接打开网站。
在Way Back Machine(Way Back Machine)中查看缓存的网页
这不完全是常规缓存。Wayback Machine实际上存储了不同网站在不同日期的不同快照。访问archive.org并在为其保留的文本框中输入网站URL。
当您输入URL并按Enter键时，它将显示拍摄了多少网站快照。它还显示您的日历，以便您可以探索网站在特定日期的外观。这些日期不会按任何特定顺序排列。它们是随机的，因为Internet Archive在不同的日子检查不同的网站。如果您想研究网站及其过去，这是一个有用的工具。您可以看到该网站在几天内是如何演变的。
还有其他免费服务，如cachedviews.com、cachedpages.com和viewcached.com，可让您选择缓存——(Cache –)例如，Google缓存、Yahoo、Bing、Live等。

How to view Archived or Cached web pages in Internet Archives
Sometimes you may want to sеe pages from the perspective of search engines. At other times, people may be offline and wаnt to check somе sites. In still other cases, people might want to see an older version of their or sоmeone’s wеb pages. All of these require you to vіew old, archived, or cаched web pages in search engine cache. The article tells уou different methods on how to view a cached web page.
View Cached web pages using Internet Archives
Before we see how to do it, let us see why search engines cache web pages.
Why do search engines cache web pages?
There are two main reasons why search engines cache web pages. The first is to manage traffic to and from their servers. Though they cache and save different screenshots on plenty of servers, there are times when the demand for a certain page is high. When a search engine has to cater to more traffic than it can handle, it falls back on cached web pages. In this case, the description of the website as seen in the results may not belong to the last indexed page.
The second purpose is to provide users with websites when they can’t be accessed. Among the reasons that make websites inaccessible are: 1) Website is down; 2) User does not have connectivity; 3) Site does not exist anymore.
Besides search engines, some websites too, create an archive of the Internet at regular intervals. They try to store as many websites as possible by indexing them and taking their snaps. This is to allow people to research a website – for e.g. how a page looked two years ago. This also enables users to view websites that now have domains changed.
View a cached web page in browsers directly
All mainstream search engines allow you to use commands in the search box, to filter search results. For example, if you wish to see if a website has content on a particular keyword, you can type:
keyword site:websiteURL
Or else you could type the following address in your browser to see the cached page directly:
http://webcache.googleusercontent.com/search?q=cache:<URL>
Likewise, to view the latest cached webpage of a website, use the cache command as follows:
Cache:URL
For example, if you wish to view a cached web page of TheWindowsClub.com, type cache:thewindowsclub.com in the address bar of your browser.
Remember that you should not enter the HTTP part of URL into the command. Not all search engines will process that. You can, however, use www and subdomains. For example, cache:news.thewindowsclub.com will show you the cached page of the news subdomain of The Windows Club.
Also, do NOT put a space before or after the full colon symbol. If you do, it will assume that CACHE is a keyword.
Use Search Results in a browser
When you search using Google, for example, you can see an inverted triangle against the URLs displayed. When you click on the triangle, you will see an option that will take you to the cached page instead of opening the website directly.
View a cached web page in Way Back Machine
This is not exactly the regular cache. The Wayback Machine is actually storing different snapshots of different websites as they looked on different dates. Visit archive.org and enter the website URL in the textbox reserved for it.
When you enter the URL and press Enter key, it will display how many snapshots of the website were taken. It shows your calendar also so that you can explore the way the website looked on a particular date. These dates won’t be in any specific order. They are random as the Internet Archive checks different websites on different days. This is a useful tool if you wish to research a website and its past. You can see how the site evolved over days.
There are other free services like cachedviews.com, cachedpages.com, and viewcached.com that let you select the Cache – eg, Google cache, Yahoo, Bing, Live, etc.
