====Bypassing filters and censorship====
If the destination server filters content based on the origin of the request, the use of a proxy can circumvent this filter.

[[File:CPT-Proxy.svg|thumb|upright=1.7|Many organizations block access to popular websites such as Facebook. Users can use proxy servers to circumvent this security. However, by connecting to proxy servers, they might be opening themselves up to danger by passing sensitive information such as personal photos and passwords through the proxy server.
