Useful Web Caching Tutorial for Webmasters

Posted · Category: CC License, Information

Recently, I have been doing research on Web Caching. And I have found Caching Tutorial for Web Authors and Webmasters , which is a detailed, informational document published by Mark Nottingham.

A Web cache sits between one or more Web servers and a client or many clients, and watches requests come by, saving copies of the responses — like HTML pages, images and files — for itself. Then, if there is another request for the same URL, it can use the response that it has, instead of asking the origin server for it again.

Web Caching can reduce latency, because the request is satisfied from the cache instead of the origin server, it takes less time for it to get the representation and display it. This makes the Web seem more responsive.

And also, Web Caching can reduce network traffic, because representations are reused, it reduces the amount of bandwidth used by a client. This saves money if the client is paying for traffic, and keeps their bandwidth requirements lower and more manageable.

You can also get more information about the type of web caches, how web caches work, how to control them, tips for building a cache-aware site and etc…

    I found this tutorial interesting and beneficial for persons who want to learn about “Web cache”. I’m one amongst them. It is

    useful and amazing tutorial because it really helped me a lot. One more point here I want to say is about the reduction in

    latency and reusing of representation, which certainly reduces the bandwidth drastically.
