Web Proxies
A proxy server is a gateway for users to the Web at large. Users
configure the proxy in their browser settings, and all HTTP requests
are routed via the proxy. Proxies are typically operated by ISPs and
network administrators, and serve several purposes: for example,
- to speed access to the Web by caching pages fetched, so that
popular pages don't have to be re-fetched for every user who views
them.
- to enable controlled access to the web for users behind a
firewall.
- to filter or transform web content.
