Web page incomplete after redirection

Hi,

 

I need to publish internal.mydomain.com/aaa/bbb as external.mydomain.com

 

I have created a policy with two rules:

 

--- FIRST RULE ---

 

HTTP host is external.mydomain.com

 

HTTP URI path is /

 

then

 

redirect to location external.mydomain.com/aaa/bbb

 

--- SECOND RULE ---

 

HTTP host is external.mydomain.com

 

then

 

forward to pool mypool

 

Initially it seems to work properly, the Internet user is taken correctly to portal login page at internal.mydomain.com/aaa/bbb. But after login, the main portal page content is not loaded, just some header parts and main menu.

 

If I remove the FIRST RULE from policy, obviously user is not redirected,and needs manually go to the correct location(/aaa/bbb), but then portal loads without issues.

 

Unfortunately I don't have access to that site and don't know it's structure. What I'm doing wrong?

 

thanks
