[Zope] Redirection problem

We have a filesystem product with an edit method that allows users to change some properties. At the end, the user is redirected to the page from which they came. Our setup has Squid in front on port 80, with Pound on port 81 load-balancing to 3 ZEO clients. No matter how we define the redirect URL - even when we hardcoded it explicitly with ':80' for test purposes - the redirection is always to port 81. What is going on? Thanks!
