HI,
I'm trying to manage presence of Win Messenger UA, but stuck at very beginning. Messenger doesn't send Expires in header and RFC3265 says it SHOULD be there, but if isn't use default value for event package (?). Ok, removed test (_m->expires==0) in function parse_hfs from subscribe.c and got response 200 OK (without Expires header and RFC says that there MUST be one), and funny NOTIFY after that. Source address of NOTIFY is from my second interface, not one that communicate with UA, but it seems that it isn't big problem. Big one is destination port which is chosen with, for me, unknown condition. So, only reply from UA computer is ICMP port unreachable. SER version is 0.9.6.
BRs, Darko
