Symptoms

Oracle Access Manager (OAM) 11g has been installed and configured for access via a load balancer / virtualhost.

One or more Oracle HTTP Server (OHS) 11g instances are configured to serve requests for the OAM managed server and WebGate 11g has been installed on the OHS.

Access to any protected application resource is failing:
- in Internet Explorer (IE) browser a blank page is shown and the browser is clearly looping around /oam/server/obrareq.cgi requests
- in Firefox browser there is a pause then error occurs: HTTP-414 Request-URI Too Large.     The URL in the address bar is e.g. http://<OAM_HOSTNAME>:<OAM_PORT>/oam/server/obrareq.cgi?encquery........
