<H1 ALIGN="CENTER">Module mod_asis</H1>
This module is contained in the <CODE>mod_asis.c</CODE> file, and
is compiled in by default. It provides for <CODE>.asis</CODE> files. Any
document with mime type <CODE>httpd/send-as-is</CODE> will be processed by
this module.
<!--%plaintext <?INDEX {\tt httpd/send-as-is} mime type> -->
<H2>Purpose</H2>
To allow file types to be defined such that Apache sends them without
adding HTTP headers.<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.
<H2>Usage</H2>
In the server configuration file, define a new mime type called
<CODE>httpd/send-as-is</CODE> <EM>e.g.</EM>
<BLOCKQUOTE><CODE>AddType httpd/send-as-is asis</CODE></BLOCKQUOTE>
this defines the <CODE>.asis</CODE> file extension as being of the new
<CODE>httpd/send-as-is</CODE> mime type. The contents of any file with a
<CODE>.asis</CODE> 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.<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.
<BLOCKQUOTE><CODE>
Status: 301 Now where did I leave that URL <BR>
Location: http://xyz.abc.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.abc.com/foo/bar.html">Joe's</A> site. <BR>
</H1> <BR>
</BODY> <BR>
</HTML>
</CODE></BLOCKQUOTE>
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 <EM>not</EM> add a Last-Modified header; it probably should.
