<summary>
<p>This module provides the handler <code>send-as-is</code>
which causes Apache HTTP Server to send the document without adding most of
the usual HTTP headers.</p>
<p>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.</p>
<p>For historical reasons, this module will also process any
file with the mime type <code>httpd/send-as-is</code>.</p>

<section id="usage"><title>Usage</title>
<p>In the server configuration file, associate files with the
<code>send-as-is</code> handler <em>e.g.</em></p>
<highlight language="config">
AddHandler send-as-is asis
</highlight>
<p>The contents of any file with a <code>.asis</code> 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 <module>mod_cgi</module> rules, so an asis
file must include valid headers, and may also use the CGI
<code>Status:</code> header to determine the HTTP response
code. The <code>Content-Length:</code> header will automatically
be inserted or, if included, corrected by httpd.</p>
<p>Here's an example of a file whose contents are sent <em>as
is</em> so as to tell the client that a file has
redirected.</p>
<example>
Status: 301 Now where did I leave that URL<br />
Location: http://xyz.example.com/foo/bar.html<br />
Content-type: text/html<br />
<br />
<html><br />
<head><br />
<title>Lame excuses'R'us</title><br />
</head><br />
<body><br />
<h1>Fred's exceptionally wonderful page has moved to<br />
<a href="http://xyz.example.com/foo/bar.html">Joe's</a>
site.<br />
</h1><br />
</body><br />
</html>
</example>
<note><title>Notes:</title>
<p>The server always adds a <code>Date:</code> and <code>Server:</code>
header to the data returned to the client, so these should not be
included in the file. The server does <em>not</em> add a
<code>Last-Modified</code> header; it probably should.</p>
