OpenText EIM Redirect Issue

Still not working. The packet trace shows that when the packet goes to the pool member, another connection is initiated to the OTDS server which is a separate server. The result is that the error "There was a problem with your request. Please contact your administrator if this persists. The DNS domains for the request and response differ or cannot be determined. As OTDS uses domain-level cookies, the request and response must originate within the same DNS domain. Please make sure that fully qualified DNS domains are specified in all configuration and browser entries. Do not use IP address or local names. The redirect URL was given as "https://contentcenter:443/OTCS/cs.exe", and the OTDS URL followed was "http://dfmspotparc.hostederp.local:8080/otdsws/login"."

The Opentext support says that the solution is a "reverse proxy", so I am taking it that when the request comes in from the client as "www.companya.com" the F5 needs to forward the request to the server as "servera.host.local". However, the OTDS server is not part of the pool as it is a separate box.
