what is the exact format for this? i have tried....
http_port=8090
http_port 8090

any help would be much appreciated, thanks in advance

From the support site:

http_port
The port number for incoming HTTP connections.  The default is 80.  When this setting has a non-default port, links to the web site will have a colon and the port number appended to the host name.

https_port
The port number for incoming HTTPS connections.  The default is 443.  When this setting has a non-default port, links to the web site will have a colon and the port number appended to the host name.

yes that is where i found the http_port info but i am still at a loss as how to actually apply it. Thanks for the reply
