You are looking at the documentation for the 1.3 version of the Apache HTTP Server, which is no longer maintained, and has been declared "end of life". If you are in fact still using the 1.3 version, please consider upgrading. The current version of the server is 2.4.
This module provides for sending files which contain their own HTTP headers.
Source File: mod_asis.c
Module Identifier: asis_module
This module provides the handler
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
This module provides no directives.
In the server configuration file, associate files with the
send-as-is handler e.g.
The contents of any file with a
AddHandler send-as-is asis
.asisextension 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
<H1>Fred's exceptionally wonderful page has moved to
<A HREF="http://xyz.example.com/foo/bar.html">Joe's</A> site.
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.
