Hello,

about module websocket, is it possible to associate a value with the TCP connection and have this value readable when handling SIP requests on that connection?

Hello, I have found a way to do it using htable.
Here is the gist of it in case someone else needs this:

loadmodule "xhttp.so"
loadmodule "websocket.so"

modparam("htable", "htable", "websocket=>size=10")

route {
if(proto == WS) {
xlog("L_DEBUG", "WebSocket check: conid=$conid val=$sht(websocket=>$conid)\n");
}
}

event_route[xhttp:request] {
if (ws_handle_handshake()) {
# successful connection
#adding $conid to hash table
$sht(websocket=>$conid) = $hu;
exit;
}
}

event_route[websocket:closed] {
xlog("L_DEBUG", "WebSocket connection from $si:$sp has closed\n");
# deleting $conid from hash table
$sht(websocket=>$conid) = $null;
}

Checking again, deletion of the entry in the hash table is failing.

In older versions of kamailio, if I am not mistaken, i used:

$sht(websocket=>$conid) = null;

but it seems in recent version null was replaced with $null (as if i use null, kamailio will not start)

so I am using

$sht(websocket=>$conid) = $null;

but it seems this doesn't work.

So, how do we currently delete an htable entry at config file?
