Newbie to Apache, someone "PLEASE HELP!!"

This is very simple to someone who knows Apache. I'm the new Admin,
never used Apache before. The previous admin used ProxyPass and
ProxyPassReverse in the httpd.conf file. My problem is that, I have 2
servers that are in a DMZ, Server "A" is the Proxy and Server
"B":5028/Folder is the host for the site. I have the homepage displayed
via Proxy (server "a"). But my issue is every sub-link and a damn java
pop-ups. So what I would like to do is just Virtual Host server "b"
through server "a". Or if someone can suggest a better aternative. I
don't know the directives or commands. Please can someone help me? I
really need it.
