CSS blame for modifying http headers

This is kind of a detailed question but here goes. Our internet complex has 2 CSS loadbalancing plenty of web farms. One site (half way across the world) receives the VIP for the web farm in the HTTP header field. The site can reproduce it consistantly, but no one else can (anywhere). The site can do anything else on the server without receiving the internal VIP address. But when it accesses a certain ASP page it gets this response. Every other http header has the DNS name. Only this one site can reproduce the problem, we have checked the ASP and all links are relative links. The CSS's are a very vanilla configuration, sticky arrow-cookie, tcp 80 keepalives, that's about it. Any ideas? Version 4.01 bld 29.
