<section id="env"><title>Environment Variables</title>

    <p>In addition to the configuration directives that control the

    behaviour of <module>mod_proxy</module>, there are a number of

    <dfn>environment variables</dfn> that control the FCGI protocol

    provider:</p>

    <dl>

        <dt>proxy-fcgi-pathinfo</dt>

        <dd>By default <module>mod_proxy_fcgi</module> will neither create

        nor export the <var>PATH_INFO</var> environment variable. This allows

        the backend FCGI server to correctly determine <var>SCRIPT_NAME</var>

        and <var>Script-URI</var> and be compliant with RFC 3875 section 3.3.

        If instead you need <module>mod_proxy_fcgi</module> to generate

        a "best guess" for <var>PATH_INFO</var>, set this env-var.

        This is a workaround for a bug in some FCGI implementations.</dd>
