<description>This module provides for executing CGI scripts based on
media type or request method.</description>

<summary>
<p>This module has two directives. The <directive
module="mod_actions">Action</directive> directive lets you run CGI
scripts whenever a file of a certain MIME content type is requested. The
<directive module="mod_actions">Script</directive> directive lets
you run CGI scripts whenever a particular method is used in a
request. This makes it much easier to execute scripts that process
files.</p>

<compatibility>The <code>virtual</code> modifier and handler passing were
introduced in Apache 2.1</compatibility>
<usage>
<p>This directive adds an action, which will activate
<var>cgi-script</var> when <var>action-type</var> is triggered by the
request. The <var>cgi-script</var> is the URL-path to a resource
that has been designated as a CGI script using <directive
module="mod_alias">ScriptAlias</directive> or <directive
module="mod_mime">AddHandler</directive>. The
<var>action-type</var> can be either a <a
href="/handler.html">handler</a> or a MIME content type. It
sends the URL and file path of the requested document using the
standard CGI <code>PATH_INFO</code> and <code>PATH_TRANSLATED</code>
environment variables. The handler used for the particular request is
passed using the <code>REDIRECT_HANDLER</code> variable.</p>
<example><title>Examples</title>
# Requests for files of a particular MIME content type:<br />
Action image/gif /cgi-bin/images.cgi<br />
<br />
# Files of a particular file extension<br />
AddHandler my-file-type .xyz<br />
Action my-file-type /cgi-bin/program.cgi<br />
</example>
<p>In the first example, requests for files with a MIME content
type of <code>image/gif</code> will be handled by the
specified cgi script <code>/cgi-bin/images.cgi</code>.</p>
<p>In the second example, requests for files with a file extension of
<code>.xyz</code> are handled by the specified cgi script
<code>/cgi-bin/program.cgi</code>.</p>
<p>The optional <code>virtual</code> modifier turns off the check
whether the requested file really exists. This is useful, for example,
if you want to use the <directive>Action</directive> directive in
virtual locations.</p>
<example><title>Example</title>
&lt;Location /news&gt;<br />
<indent>
SetHandler news-handler<br />
Action news-handler /cgi-bin/news.cgi virtual<br />
</indent>

<name>Script</name>
<description>Activates a CGI script for a particular request
method.</description>
<syntax>Script <var>method</var> <var>cgi-script</var></syntax>

<context>server config</context><context>virtual host</context>
<context>directory</context></contextlist>
<usage>
<p>This directive adds an action, which will activate
<var>cgi-script</var> when a file is requested using the method of
<var>method</var>. The <var>cgi-script</var> is the URL-path to a
resource that has been designated as a CGI script using <directive
module="mod_alias">ScriptAlias</directive> or <directive
module="mod_mime">AddHandler</directive>. The URL and
file path of the requested document is sent using the standard CGI
<code>PATH_INFO</code> and <code>PATH_TRANSLATED</code> environment
variables.</p>
<note>
Any arbitrary method name may be used. <strong>Method names are
case-sensitive</strong>, so <code>Script PUT</code> and
<code>Script put</code> have two entirely different
effects.
</note>
<p>Note that the <directive>Script</directive> command defines default
actions only. If a CGI script is called, or some other resource that is
capable of handling the requested method internally, it will do
so. Also note that <directive>Script</directive> with a method of
<code>GET</code> will only be called if there are query arguments present
(<em>e.g.</em>, foo.html?hi). Otherwise, the request will
proceed normally.</p>
<example><title>Examples</title>
# For &lt;ISINDEX&gt;-style searching<br />
Script GET /cgi-bin/search<br />
<br />
# A CGI PUT handler<br />
Script PUT /~bob/put.cgi<br />
