We have a War called login when has a picketlink.xml

There is a web war which also has a picket link.xml.

Everything works ok with the single link - https://abccompany.com

But now we need to add our client specific login pages like

https://ourclient1.com and https://outclient2.com

This cannot be done because the login war sees only "https://abccompany.com" and forwards "https://ourclient1.com/" and "https://ourclient2.com/ " to https://abccompany.com/

How would I do the dynamic forwarding for multiple pages?

Thanks
