# Module mod_asis

This module is contained in the `mod_asis.c` file, and is compiled in by default. It provides for `.asis` files. Any document with mime type `httpd/send-as-is` will be processed by this module.

## Purpose

To allow file types to be defined such that Apache sends them without adding 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.

## Usage

In the server configuration file, define a new mime type called `httpd/send-as-is` e.g.

> `AddType httpd/send-as-is asis`

this defines the `.asis` file extension as being of the new `httpd/send-as-is` mime type. 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.
