Hi, Thanks for the pointers. Got it to work. For the record, what I did: * add "name sock_tls" to the listen= parameter * set tcp_reuse_port=yes * the handler for OPTIONS saves the remote port to $shv(port__XXX) * my call handler sets $fsn="sock_tls" and $rp to $shv(port__XXX) … and that's it. So that was easier than expected. NB, when browsing the sources for this I noticed that the "tcp_reuse_port" option is not recognized at all if the OS does not support SO_REUSEPORT. However, here we're re-using an existing connection instead of opening a new connection from a port that has existing connections. Thus on systems that don't have SO_REUSEPORT (some BSDs, AFAIK) this method doesn't work (but should). This mismatch is also the reason why I didn't notice this option in the documentation … -- -- Matthias Urlichs
