APC (Alternative PHP Cache) is a PHP opcode cache. It stores PHP pages in RAM and reduces hard disk activity. This makes a real difference to the performance in Moodle, and you should be able to achieve a 50% increase in system capacity and your CPU will be 50% less busy. This guide is for installation of APC on a Windows server. The instructions have been tested on a Windows 2003 server, and they should also be applicable if you are using Windows XP as a test server.

Really Simple History is a lightweight JavaScript library for the management of bookmarking and browser history in Ajax/DHTML applications. RSH serializes application data in an internal JavaScript cache so that bookmarks and the back button can be used to return your application to an earlier state. Originally developed by Brad Neuberg in 2005, RSH has won a large user base for its simplicity, ease of use and lack of dependency on any specific Ajax framework. It's written in plain old JavaScript and can be included on any site according to the terms of its BSD license. In September 2007, Brian Dillard of Pathfinder Development came on board as maintainer and ongoing code steward for the project. A new version, with support for additional modern browsers (IE7, Safari, Opera), was released as RSH 0.6 on December 3, 2007.

A Web cache sits between one or more Web servers (also known as origin servers) and a client or many clients, and watches requests come by, saving copies of the responses — like HTML pages, images and files (collectively known as representations) — 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.

Caching is a great example of the ubiquitous time-space tradeoff in programming. You can save time by using space to store results. In the case of websites, the browser can save a copy of images, stylesheets, javascript or the entire page. The next time the user needs that resource (such as a script or logo that appears on every page), the browser doesn’t have to download it again. Fewer downloads means a faster, happier site.

This document describes reverse proxies, and how they are used to improve Web server performance. Section 1 gives an introduction to reverse proxies, describing what they are and what they are used for. Section 2 compares reverse proxy caches with standard and transparent proxy caches, explaining the different functionality each provides. Section 3 illustrates how the reverse proxy actually caches the content and delivers it to the client. Section 4 describes how to configure Squid as a reverse proxy cache.

In this article, Andres March shows how OSCache can be used to save your processing requirement by storing data or content, to prevent continually re-reading it or re-generating it, including a quick walkthrough of what OSCache can do, through caching objects, entire HTTP responses, or fragments of HTTP via a JSP tag library.
