Apache and Tomcat issue

Hi guys,
I am new here and I liked a lot hits application so I am starting to install it for my company.

I have Apache WebServer, listening in port 80.
Going to the domain https://mydomain.com/BuildServer I want that the request is redirected to Tomcat (http://localhost:8090/BuildServer).

In Apache WebServer the httpd.conf is

ProxyRequests Off
ProxyPass /BuildServer http://localhost:8090/BuildServer
ProxyPassReverse /BuildServer http://localhost:8090/BuildServer

<Connector useBodyEncodingForURI="true"
.... />

<Context path="BuildServer" docBase="c:/Tomcat 6.0/webapps/BuildServer">

• if I go to static resources like https://mydomain.com/BuildServer/img/add.gif: WORKS
• when i start Tomcat and go to https://mydomain.com/BuildServer I see the initialisation page saying "TeamCity is starting": WORKS
• once it finishes the initialization is not able to retrieve the page https://mydomain.com/BuildServer/login.html: WHY

Could anybody help me for this issue? I am not able to understand it.

Is it a problem with HTTPS?

MANY MANY thanks
