Client browser through APM portal access does not get server cookie

Hello everyone

 

Maybe someone can help shine a light on a problem I have

 

External Big IP with APM VS for web-portal.mydomain.com using an acess policy with webtop and Portal Access Portal Access URI is like

 

myapp.mydomain.intra DNS entry is the address of a VS on the Internal Big IP Load balancing only VS

 

When using the Internal VS drectly, browser gets the JSESSIONID cookie

 

But when accessing the app through the External VS with the Portal Access We don't see the JSESSIONID cookie in the browser

 

Could it be related to the different domain or the path set in the cookie?

 

Any setting required to make the cookie go to the client?

 

So, I hope someone can point in the right direction

 

Thanks
