sapwebdisp configuration

Hi all, im looking for a hint or solution on how to achieve our planned setup, whether some one have tried it before.

Our backend is : SAP NW J2ee 7.00 ( Java stack only ) SP 12 with SLL applied to the system.

eg: server CN is : j2eeapps.yyy.com , SSL also enabled on this server.

we have develop applicaitions on it , and for the internet publishing we are using sapwebdisp.

The question is :

how can i do multiple redirection on the sapwebdisp.pfl ?

we will be having mulltiple URL

eg.

1. https://app1.aaa.com shoudl go to /webdynpro/dispacther/app1

2. https://app2.aaa.com should go to /webdynpro/dispacther/app2

if user type http://app1.aaa.com it also will be redirectted to SSL https://j2eeapps.yyy.com/webdynpro/dispacther/app1

is this possible in sapwebdisp ?

Thanks..
