HTTP proxy server is a proxy allowing to work on the Internet with HTTP and (not always) FTP protocols. It can carry out caching of information downloaded from the Internet. Now HTTP proxy servers are the most widespread. Their support (ability to use them) is included into many programs: browsers, download managers etc. However, their support is not realized at a level of an operating system – in order to use them, you should configure all programs, which should use proxies, in an appropriate way.
