Symptoms

Oracle HTTP Server 11g (11.1.1.4+) 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). Original symptoms started on these versions because of security change on WLS. The same issues can occur on any version, including 12c and there are actually different reasons and related solutions for these causes. Issues are usually seen when SSL is configured with the Oracle HTTP Server (or other lbr/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.
