This article describes how to add WL-Proxy-SSL HTTP header to meet case requirement below.

Based on Oracle WebLogic documentation indicates, with proxy-ssl deployment setup in-front of WebLogic server, it requires to have WLProxySSL parameter is set to ON to maintain SSL communication between the plug-in and WebLogic Server when the following conditions exist:
- A HTTP client request specifies the HTTPS protocol.
- The request is passed through one or more proxy servers (including the Oracle WebLogic Server Proxy Plug-In).
- The connection between the plug-in and WebLogic Server uses the HTTP protocol.
