    <p>This directive now allows a port to be added to the

    server name.  This allows an admin to assign the canonical

    port at the same time that the canonical name is assigned.

    The Port directive in Apache-1.3, which used to perform this role, has also

    been removed, easing configuration for all users.</p>

    If no port was specified, Apache implies port 80 for http://

    and port 443 for https:// requests.<br>

    <p>See the description of the

    <a href="#usecanonicalname">UseCanonicalName</a> directive for

    settings which determine whether self-referential URL's (e.g., by the

    <a href="mod_dir.html">mod_dir</a> module) will use the specified

    port, or the port to which the client connected.

    <a href="mod_dir.html">mod_dir</a> module) will refer to the

    specified port, or to the port number given in the client's request.
