need help with Tomcat and apache integration

hi

I am using tomcat application server (with 2 instances), apache webserver, load balancer.
ssl offloading is done at load balancer end i am not carrying it on webserver or application server

I have an url https://xyz.abc.net/.................................
which is functioned to open two windows one with a welcome page and other with a begin page of our apllication

I am getting a window welcome page, other window is coming with a message "page cannot be displayed"
when i checked the url of the corresponding window i noticed its redirecting it to http://xyz.abc.net/.................................

So i edited server.xml file by appending
secure="true" and scheme="https"
when i launch the url above process is repeating but URL of the window with a message "page cannot be displayed" is
https://xyz.abc.net:80/.................................

If i edit both above urls properly by making http to https and by removing the port number application is launching properly

i am using two ports 8009 and 8010 for 2 tomcat instances, webserver is listening 8000 port
Please anyone help me in resolving the issue
