They're manageable if you know all the ins and outs. The big advantage is speed, as they avoid the cost of establishing the initial TCP connection and logging in. In my experiments, this cut the run time for the average script in half. But you have to deal with managing an overwhelming # of perpetually open connections, which takes a lot of resources on both the server and the client side, in addition to problems like connection settings persisting from one script to the next. My opinion is avoid them unless you have a demonstrated need for the speed increase. In that case, make sure you have the time to understand and code for all the potential issues. -- Bill Moran Collaborative Fusion Inc. http://people.collaborativefusion.com/~wmoran/ [EMAIL PROTECTED] Phone: 412-422-3463x4023 **************************************************************** IMPORTANT: This message contains confidential information and is intended only for the individual named.
