Applies to:Oracle WebLogic Server - Version 10.3.4 and later
Oracle Forms - Version 220.127.116.11.0 and later

Information in this document applies to any platform.
This note was written for 11g but it also applies to 12c.
Oracle HTTP Server 11g (126.96.36.199+) is installed and using mod_wl_ohs (WebLogic Server Plugin 1.1, also versioned 11.1.1.x) to connect to a Java application deployed on Oracle WebLogic Server 10.3.4 (or later). SSL is configured with the Oracle HTTP Server (or other webserver/proxy) and forwarding requests to Oracle WebLogic Server (WLS) where SSL may not be configured.
- The primary symptom is url in HTTP instead of an HTTPS. Any redirection mechanism in place to enforce HTTPS may end up seeing the symptom of a looping redirect.
- Investigating further into the processing, its continually going from HTTPS to HTTP and repeating.
- You may also see a "HTTP/1.1 302 Moved Temporarily" from a browser and see a "NZ Library Error: Unknown error" entry in the OHS logs.
