Simpler URL for Websphere Portal

[leithp]

We're kind of excited about the prospect of dropping our gateway servers.  We have cognos 11 installed in a sandbox environment, using the default url format: https://mycogserver.domain.org:9343/bi

With older installs, I knew IIS well, and I could slip a default.asp or default.htm in the wwwroot folder and have a hit on the default server url, say, http://mycogserver.domain.org redirect the user to https://mycogserver.domain.org/cognos/cgi-bin/cognosisapi.dll ... of course, in the case of cognos 11, I'd want it to redirect them to https://mycogserver.domain.org:9343/bi

Has anybody played with this, or run across any documentation telling us how we might do this?
