Apache Module mod_asis
Summary
    This module provides the handler send-as-is
    which causes Apache to send the document without adding most of
    the usual HTTP headers.
    This can be used to send any kind of data from the server,
    including redirects and other special HTTP responses, without
    requiring a cgi-script or an nph script.
    For historical reasons, this module will also process any
    file with the mime type httpd/send-as-is.
Directives
This module provides no directives.

    In the server configuration file, associate files with the
    send-as-is handler e.g.
    AddHandler send-as-is asis
The contents of any file with a .asis extension
    will then be sent by Apache to the client with almost no
    changes. Clients will need HTTP headers to be attached, so do
    not forget them. A Status: header is also required; the data
    should be the 3-digit HTTP response code, followed by a textual
    message.
    Here's an example of a file whose contents are sent as
    is so as to tell the client that a file has
    redirected.
    
      Status: 301 Now where did I leave that URL
      Location: http://xyz.abc.com/foo/bar.html
      Content-type: text/html
      
      <html>
      <head>
      <title>Lame excuses'R'us</title>
      </head>
      <body>
      <h1>Fred's exceptionally wonderful page has moved to
      <a href="http://xyz.abc.com/foo/bar.html">Joe's</a>
      site.
      </h1>
      </body>
      </html>
    
Notes:
    The server always adds a Date: and Server:
    header to the data returned to the client, so these should not be
    included in the file. The server does not add a
    Last-Modified header; it probably should.
