@miconda I found a simple way to get the value of the X-Forwarded-For header
without changing the code in the websocket module.
I thought about this after reading again the comment for Juha.
I'm retrieving the X-Forwarded-For header in the event:xhttp and use htable to
track the conid

This patch is working for 5.x and master branch.
I have also 2 backported patches for 4.4 and 4.3.
Should I create 2 pull requests?

New feature to get the real source IP when kamailio websocket is behind a load
balancer transmitting X-Forwarded-For and/or X-Real-IP headers:
Detect HTTP headers X-Forwarded-For and X-Real-IP during the Websocket
handshake.
The pseudo variables $ws_real_src_ip is populated during ws_handshake()
