URL redirection

URL redirection
URL forwarding

   <World-Wide Web> (Or "URL forwarding")

   When a {web server} tells the {client} {browser} to obtain a
   certain requested page from a different location.  This is
   controlled by {directives} in the server's configuration files
   or a "Location: header output by a {CGI} script.

   The web server stores all its documents in a {directory tree}
   rooted at some configured directory, known as its "document
   root".  Normally the {URI} part of the {URL} (the part after
   the {hostname}) is used as a {relative path} from the document
   root to the desired file or directory.  A redirect directive
   allows the server administrator to specify exceptions to this
   general mapping from URL to file name by telling the browser
   "try this URL instead".  The new URL may be on the same server
   or a different one and may itself be subject to redirection.

   The user is normally unaware of this process except that it
   may introduce extra delay while the browser sends the new
   request and the browser will usually display the new URL
   rather than the one the user originally requested.
