[SR-Users] pipelimit: inexistent pipe error logs

Tue Jan 21 16:31:30 CET 2020

Hi Daniel,

Thanks for your feedback.
I have a dedicated listen directive for JSONRPC
listen = 127.0.0.1:8000

and then an event_route for it:
event_route[xhttp:request] {
    if ($Rp != 8000) {
        xhttp_reply("403", "Forbidden", "text/html",
"<html><body>Forbidden</body></html>");
        exit;
    }
    if ($hu =~ "^/RPC") {
        jsonrpc_dispatch();
    } else {
        xhttp_reply("200", "OK", "text/html", "<html><body>Wrong URL
$hu</body></html>");
    }
    return;
}

So, I'm already doing HTTP traffic only in port 8000.
The interesting part is that if I use kamcmd pl.list pipe_INVITE, only the
first log line is printed. Using curl, I see the other 2 logs all the time.

Thank you
