A '''web accelerator''' is a [[proxy server]] that reduces [[web site]] [[access time]]s. Web accelerators may use several techniques to achieve this reduction:

A '''web accelerator''' is a [[proxy server]] that reduces [[web site]] [[access time]]s. It is similar to an operating system cache but meant for website delivery, that is, an intermediate between the web server and the scripting language that performs caching functions that aid in allowing web scripts to be delivered the requesting client faster than without the accelerator. The only drawback to this system is that if web scripts are constantly changed the cache needs to be emptied to ensure only the new versions of server scripts are sent to the client.

Web accelerators may use several techniques to achieve this reduction:

* They may [[web cache|cache]] recently or frequently accessed [[electronic document|documents]] so they may be sent to the [[client (computing)|client]] with less [[latency]] or at a faster [[transfer rate]] than the remote [[server (computing)|server]] could.

* They may [[link prefetching|prefetch]] documents that are likely to be accessed in the near future.

These applications generally serve to improve [[dial-up]] speeds, however [[Google]]'s [[Google_Web_Accelerator|Web Accelerator]] is specifically designed for improving [[broadband]] access to the sites. Moreover they are limited to websites only and cannot improve speeds of [[downloads]] or [[streaming]] or any other internet applications.
