[sr-dev] Fwd: [OpenSIPS-Devel] Avoiding creating outgoing TCP connections for NOTIFY requests

When looking up the location for a user all flags will be loaded, so if we specified the said flag when the user was registered a new connection will not be attempted if there is no connection. However AFAIK this doesn't apply to NOTIFY requests generated by OpenSIPS when using presence. Scenario is simple: user subscribes using TCP, her connection breaks, someone sends a PUBLISH. OpenSIPS will try to open a connection to deliver the NOTIFY. This is what I'd like to avoid. First thing that comes to my mind is reusing the idea with tcp_no_new_conn_bflag, so if a user sets if before calling handle_subscribe, in-dialog NOTIFY requests would not attempt to create the connection. Thoughts, proposals, patches are welcome :-) Regards, -- Saúl Ibarra Corretgé AG Projects _______________________________________________ Devel mailing list Devel(a)lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/devel
