A Guide to Web Caches

Web cache can be compared to a personal address book. In any phonebook, all your contact numbers are listed. To gain quicker access, one must maintain a list of numbers they can frequently contact. When studying computer science, the amount of data emitted is reduced by caching. An excellent example of a caching system is your computer RAM.


Web caches are stationed between a client’s browser and their web server. The web caches can save copies of resources such as scripts, as they pass on. Anytime client requests for these resources, the web cache can provide it rather than having to forward the request to the original web server. On a side note, as you may already know, internet users can utilize google history clean internet explorer if they wish to clean their caches.


How can One Make the Most of Caching?

It is quite impossible to avoid caching so you might as well just make the most of it. Many might ask themselves whether it is worth the effort. First, remember that HTML tags are not as effective as most imagine them to be. Additionally, the Pragma HTTP headers work poorly too.

How Useful are Web Caches?

Misunderstood web caches can be disenfranchising to web programmers. This is why it is vital for web programmers to understand the importance of web caches fully. The main reason for using web caches is to Reduce latency. Intermediate caches, which are closer to your clients than from the servers, can save a great deal of content. They will take much less time to reach clients. This makes such websites more responsive. To reduce network traffic, several resources can be used without the need to obtain information from the servers. Caching will reduce the amount of bandwidth that is consumed by each client. There are three primary levels of cache.

Web Browser Cache

INTERNET 2The first cache layer is your web browser. Every time you open up a new page, a trail of the resources form that web page is recorded on your hard drive. Anytime that resource is requested within the same browsing session, in a few seconds the browser will have sourced out the local copy. The cache is preferred when the user selects the back button. Similarly, when using a similar header graphic on each page, it gets downloaded resulting in quicker page-load times.

Proxy Cache

The proxy cache operates similarly to the browser cache. The primary distinction is the fact that proxy caches are communally shared to many clients. This means when thousands of browsers load a site while you are still in session, their requests do not have to be sent to the web browser. Instead, their requests are serviced by the proxy server. One can modify the proxy settings on the preferences tab of the browsers. Otherwise, it is automatically set by the underlying network intermediaries.


Similar to intermediaries, the gateway caches are not deployed through network administrators. Instead, they are managed by webmasters who would like to scale their sites to increase their reliability.…
