omnifaces

 - 

Available since OmniFaces 2.1

Collection of EL shortcut functions for obtaining information from the current HTTP request which isn't directly available via #{request} and thus otherwise requires some string concatenating and/or substringing.

The difference between #{of:getRemoteAddr()} and #{request.remoteAddr} is that the OmniFaces function recognizes and filters X-Forwarded-For header coming from proxies.
