  proxy server
  
     <programming, World-Wide Web> A process providing a cache of
     items available on other servers which are presumably slower
     or more expensive to access.
  
     This term is used particularly for a World-Wide Web server
     which accepts URLs with a special prefix.  When it receives
     a request for such a URL, it strips off the prefix and looks
     for the resulting URL in its local cache.  If found, it
     returns the document immediately, otherwise it fetches it from
     the remote server, saves a copy in the cache and returns it to
     the requester.  The cache will usually have an expiry
     algorithm which flushes documents according to their age,
     size, and access history.
  
     Compare proxy gateway.
