Traffic breaks coming back from https to http after enabling X-Forward header for weblogic server

Having poured through some searches on the subject, I would definitely agree with Nitass. There must be something in the application logic that is causing the break. I would highly recommend having a look at both the client side traffic (via something like HTTPWatch or Fiddler in the browser) and the server logs to see if there's something about the WL-Proxy-Client-IP header that the HTTP site doesn't like after returning from the HTTPS site.
