Apache HTTP Server Version 2.4

| Description: | Sends files that contain their own HTTP headers | 
|---|---|
| Status: | Base | 
| Module Identifier: | asis_module | 
| Source File: | mod_asis.c | 
This module provides the handler send-as-is
    which causes Apache HTTP Server 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.
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 httpd to the client with almost no
    changes. In particular, HTTP headers are derived from the file
    itself according to mod_cgi rules, so an asis
    file must include valid headers, and may also use the CGI
    Status: header to determine the HTTP response
    code. The Content-Length: header will automatically
    be inserted or, if included, corrected by httpd.
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.example.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.example.com/foo/bar.html">Joe's</a>
      site.
      </h1>
      </body>
      </html>
    
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.
