Hello Marcos,
You misunderstood the information I've sent.
I dit not mean that you must run the Web Dispatcher at the same server as the Enterprise Portal.
What I meant is that your users must use an URL that points to the Web Dispatcher, and that the HOST option of the redirect parameter must point to the Web Dispatcher itself.
Your end users should never need to access/know the URL that points directly to the Portal, they must always use the URL that points to the Web Dispatcher.
Regards,
Isaias
