JR,
Like many lookup functions, the alias_db_lookup() function has a return value. You should check it for a negative result before proceeding further in the script:
Example:
if(!alias_db_lookup("dbaliases")) { sl_send_reply("404", "Not Found"); exit; }
Error handling in general is a must.

Hi All,
I have a real simple load balancer proxy setup using the dispatcher module, works great. I want to do an alias lookup before I send the calls through to the dispatcher, but I can't seem to find a good example of how that should be setup in the config script. I've tried different things, the aliase_db_lookup is working but if a user is not in the database, the call loops and does not continue on to the dispatcher. Here is my current route script (this does not work):
route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; };
alias_db_lookup("dbaliases"); t_on_failure("1"); t_relay(); ds_select_dst("1", "4"); t_on_failure("1"); t_relay();}
failure_route[1] { ds_next_dst(); forward(); } I think there should be an 'if' 'then' or 'if' 'else' separating the alias_db_lookup and the ds_select functions, but I'm not sure of the syntax and where the curly brackets need to be.
Thanks.
