We are trying to use DNS SRV records to load balance outbound transactions across 2 or more servers. Something like this: UA => SER => (Some processing logic) => Back to SER after a 300 Redirect which contains a Contact phone number and IP/DNS at which to contact the contact => DNS SRV lookup for the contact IP and send it to one of the two servers returned by the DNS lookup. So this last leg is where we have to load balance multiple contact IP servers and we were trying to use DNS SRV for that. We haven't seen any success in this, it does load balance when both are up. But as soon as only one server is up, SER keeps trying to reach the first one which is down and never tries to reach the second one. Ultimately the transaction times out. Has anybody had success in implementing this kind of scenario for load balancing with DNS SRV? Is anything else besides using DNS SRV an option? Thanks in advance!! __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com
