Symptoms

1. After configuring Apache Reverse proxy following note ID 422359.1.
2. Portal(/pls/portal) and SSO urls (such as /sso,/pls/orasso,/oiddas) and mod_osso protecting static pages where SSO/DAS run are working fine. Lets say follow

URL’s protected with SSO work fine:

http://myproxy.vm.oracle.com:8888/oiddas
http://myproxy.vm.oracle.com:8888/pls/orasso
http://myproxy.vm.oracle.com:8888/private/index.html ---> Static page on SSO/DAS server (mod_osso)
http://myproxy.vm.oracle.com:8888/pls/porta/

3. But whenever any static resource protected by mod_osso loaded by OHS running in the Portal middle the SSO page comes up. After entering username/password

the page just hangs. Lets says follow URL presenting issue:

 http://myproxy.vm.oracle.com:8888/private2/index.html ---> Static page on OHS/Portal middle tier server (mod_osso) presenting issue.
