Hi,

What I get is this error message:

do_action(): ERROR: do action: forward: bad uri transport 5

Is there anything special I need to do? Does forward() maybe just not
understand WS transport?

Alright, I think I found it. It seems like there is an issue in action.c where PROTO_WS and PROTO_WSS are not handled. This patch solves it for me, however it's just a proof of concept as I don't know enough of the core and WS implementation to understand the implications:

 #endif

With that patch in place, I can set $fs to my local tcp socket, like

        $fs="tcp:192.168.51.133:5060";

and let $du point to the right destination, like

        $du="ws:192.168.51.1:1234";

and the request is forwarded correctly.

Any feedback on this?

Andreas
