[OmniFaces utilities (2.3/2.0)] Get the Internet Protocol (IP) address of the client that sent the request

---

[OmniFaces utilities] The getRemoteAddr() method returns the Internet Protocol (IP) address of the client that sent the request. This will first check the X-Forwarded-For request header and if it's present, then return its first IP address, else just return HttpServletRequest#getRemoteAddr() unmodified.

Starting with OmniFaces 2.3 this method is available in Servlets utility class also as, Servlets#getRemoteAddr().
