HTTPS problem with Portal behind WebDispatcher

Hi everyone,

I'm using a SAP WebDispatcher to provide access to an Enterprise Portal. The problem is, I have to use HTTPS and no HTTP at all. The HTTPS access to the WebDispatcher works fine. When I type the URL https://<mywebdispatcher>/sap/admin everything works as expected.

But when I try to access the portal by typing https://<mywebdispatcher>, I get instantly redirected to a non-HTTPS connection (http://<mywebdispatcher>/irj/portal). The parameter I use is:

icm/HTTP/redirect_0 PREFIX=/, TO=/irj

If I use:

icm/HTTP/redirect_0 PREFIX=/, TO=/irj/portal

the logon screen is still HTTPS but the next then again is not.

I can't dactivate the HTTP service of the WebDispatcher, because I get a "page not found" after the redirection.

I am able to switch between HTTP and HTTPS at any time, once I have logged in.

What else do I have to do or what did I forget?

Thanks in advance,

Michael
