- proxy server
A server that sits between a client application, such as a web browser, and a real server. A proxy server stores copies of webpages that you access so that they can be brought up more quickly when you want to access them again. When you ask for a webpage, the proxy server checks to see if the webpage is stored in its cache. If it is, it returns that copy, without having to access the internet. If not, it forwards the request to the real server. Proxies do speed up access considerably, but depending on how the proxy server is configured, they may sometimes bring up stored older versions of websites, without showing changes made in the last few hours.
