When we enable SSL between the proxy and WebLogic Server through Trusted CA certs, it fails to load the Trusted CA file.

In this case, customer is using their own trusted CA certs at WebLogic Server side and they need to enable SSL between Apache (Version 2.2.14) Web Server and WLS.

When we try to access the WLS console through the proxy, we get the following message in the browser:

412 Precondition Failed
The precondition on the request for the URL/console evaluated to false.

In the proxy log, we can see the following message:

================New Request: [GET /console HTTP/1.1] =================
