<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 <glossary
    ref="mime-type">MIME content type</glossary> 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> </summary>

<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 <glossary
    ref="mime-type">MIME content type</glossary>. 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>
      &lt;/Location&gt;
    </example>

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