Publishing multiple SSL webs through ISA 2006

[achen]

We have successfully published our first web (Sharepoint) base on Form
Based Authentication through ISA 2006, the next agenda seems not too
difficult, but I can't figure out how to accomplish it.

We have external name www.company.com, a SSL certificate under that CN
was installed on ISA server. If a user types http://www.company.com,
he will be taken to the regular web page. If he types https://www.company.com,
he will be taken to a FBA page, which directs him to our Sharepoint
site after logging in. Everything works fine after this point.

What I like to do next, is publishing multiple webs through FBA at
different URL paths, for example:

When accessing https://www.company.com/sp -> form authenticate -> Be
taken to Sharepoint site
When accessing https://www.company.com/owa -> form authenticate -> Be
taken to OWA site
When accessing https://www.company.com/citrix -> form authenticate ->
Be taken to Citrix site

I tried creating additional Web Publishing Rules using the same web
listener which worked for Sharepoint, but they didn't work. I can't
even modify the existing one and have it work under URL
https://www.company.com/{anything} other than straight https://www.company.com/

Some additional hints would he appreciated, thank you !
