I am an OP in a channel that is mainly visited by people using a Java client integrated into a web site. I am writing an entry script to identify previous visitors but am stumped because it appears the Java clients change someones address every time they log in. eg. User 1 comes in (get address), they disconnect and they immediately re-connect and the IP portion of their address is different. So, my question is, does anyone know a way around this? Is there any way to query a user that will always return consistent and unique information?

Thanks.
