Multiple Web Pages on single server

I have a case where I have two web pages that are hosted on the same web server. The first application is /index.jsp, and the second is /pkl/index.jsp. I am trying to figure out how to get the traffic to the right directory based on the url.

 

 

Site 1 site1.portal.hca.com to /index.jsp

 

Site 2 iphone.portal.hca.com to /pkl/index.jsp

 

 

Any help is appreciated.
