Incorrect _SERVER['SERVER_PORT'] returned??

Hello. I have configured my RHEL5 Apache system with SSL. I verified that SSL was installed correctly and accessing the site via SSL works as expected. The problem I am having is my PHP code is pulling the $_SERVER['SERVER_PORT'] variable and this is coming back as 80 rather than 443. Here is my <VIRTUALHOST> code within HTTPD.CONF <VirtualHost *:443> ServerAdmin first.name@xyz.com DocumentRoot /var/www/html/redcap ServerName name.url.edu ErrorLog logs/<filename> CustomLog logs/<filename> </VirtualHost> I can get 443 to be returned from _SERVER['SERVER_PORT'] if I edit the 3rd line above to : ServerName name.url.edu:443 But, if I do this, it messes a few other things up internal to the site. Does anyone have an idea why _SERVER['SERVER_PORT'] is returning 80 rather than 443? Any thoughts would be much appreciated. Regards,
