Authentication "pop-up" window breaks OHS->WebLogic proxy

I have setup an app on WebLogic (11g) with OHS as the front end. The app is over SSL.

Scenario 1 : I deploy the app on WebLogic, setup OHS as reverse proxy and access it from a browser. Everything is good.

Scenario 2 : The app is modified to include authentication in the fo开发者_开发技巧rm of a "pop-up" window. Once I deploy this app on WebLogic, I cannot access it from OHS. I can access it via WebLogic but not OHS.

Thinking this is related to DynamicServerList, I turned it off, but it did not help.

Has anyone resolved this?

Problem was solved by enabling WebLogic plugin on the WLS managed servers.
