Hi everyone I think my issue could be fixed with mod_xml_curl but I'm using FS purely through sockets (inbound mode) When I get the park event, I execute some biz logic. Leg's A source IP plays a role in this logic so based on the value of the IP (a big pool of allowed IP addresses is generated dynamically and changes very fast so I have a logic to query this pool) all good so far. However, if the incoming channel’s source IP is not allowed I would still want to answer and continue on but I must challenge it with a user name and password that I have a logic to retrieve. Any thoughts on how should I go about doing the username/password challenge through the socket without starting a new listening socket for mod_xml_curl requests . I really appreciate any thoughts on this issue Many Thanks,
