For example if a user requests to go onto page 1 then later another user sends a request for the same page, instead of sending the request to the webserver the proxy will just return the page 1 it got off the first user and send it to the second, so it re-uses requests. It also filters requests and a company can manage what their employers go on by using a proxy. (Beal, n.d.)
