Proxy Server

September 6, 2007

A proxy server sits between the user’s computer and the internet. It holds requests from users for a length of time and can be used in several situations, including:

Caching. A proxy server can store pages that you, or other people in your organisation, have already viewed on the web. This is called caching and it means that when you try to view a page that has been viewed previously, it can be retrieved from the cache on the proxy server not from the website it is actually from (which would take longer). In a large organisation with many web users this can significantly improve web performance.

Blocking. A proxy server can also be used for administration purposes, for example to prevent users from visiting specific websites.

Anonymising. Some web users use a proxy server to enable them to browse the web anonymously.

The average user will be unaware that their requests are going through a proxy server – a webpage will still look as if it has come from the actual website, with the website URL.
