Closed Issues in 2.3.0 HF-004 (This Release)

TEA-3252
If you logged in to the TIBCO Enterprise Administrator server when the proxy was 
running on HTTPS protocol and the server was running on HTTP protocol, an HTTP 
code error occurred after a successful login. This error occurred because the 
server did not support the 'X-forwarded-proto' configuration through Jetty.
