<compatibility>Available in Apache 2.1.5 and later.

On Windows from Apache 2.3.3 and later.</compatibility>

<usage>

    <p>This directive specifies the protocol used for a specific listening socket.

       The protocol is used to determine which module should handle a request, and

       to apply protocol specific optimizations with the <directive>AcceptFilter</directive>

       directive.</p>

    <p>You only need to set the protocol if you are running on non-standard ports, otherwise <code>http</code> is assumed for port 80 and <code>https</code> for port 443.</p>

    <p>For example, if you are running <code>https</code> on a non-standard port, specify the protocol explicitly:</p>

    <example>

      Protocol https

    </example>

    <p>You can also specify the protocol using the <directive module="mpm_common">Listen</directive> directive.</p>
