Reverse Proxy




Contrast this with 'forward proxy', which is a proxy server configured in the end-user's browser.

There are several reasons for installing reverse proxy servers:
  • Security: the proxy server is an additional layer of defense and therefore protects the webservers further up the chain

  • Encryption / s are created, the SSL encryption is sometimes not done by the webserver itself, but by a reverse proxy that is equipped with SSL acceleration hardware.

  • s, the reverse proxy may have to rewrite the URLs in each webpage (translation from externally known URLs to the internal locations).

  • s of this sort can often satisfy a considerable amount of website requests, greatly reducing the load on the central web server.

  • Compression: the proxy server can optimize and compress the content to speed up the load time.

  • Spoon feeding: a dynamically generated page can be produced all at once and served to the reverse-proxy, which can then return it to the client a little bit at a time. The program that generates the page is not forced to remain open and tying up server resources during the possibly extended time the client requires to complete the file transfer.
