Apache 2.0.28 and 2.0.29-dev from CVS on 29-Nov-2001.
>Description:
If I use Port in my config Apache argues, that the Port directive isn't supported anymore. So I just use the Listen directive to set my Apache to run on port 8042. But if output the CGI environment variable SERVER_PORT via the SSI command #echo var="SERVER_PORT", I still get the "80" which was set via ./configure and AFAIK has been compiled into the apache httpd binary.
>How-To-Repeat:
See the example and footer on http://xcip3.studcs.uni-sb.de:8042/.
The sources of these SSI pages are also available there. See the bottom of the mentioned pages.
[If the host is down, try cip117 instead of xcip3.]
>Fix:
IMHO the value of SERVER_PORT should be set to the Port which the acutal request came in and not to some configured "default" value. Perhaps there should be a second CGI environment variable called "DEFAULT_PORT" or "SERVER_PORT_DEFAULT" which results in the default port (probably the first parameter to Listen in the vhost config section).
