Hi all -<br><br>I have a few newbie questions regarding gen_server and gen_fsm - I couldn't find the answers easily though I'm sure they exists somewhere; would appreciate pointers and sharing of experiences in designs :)
<br><br>* are gen_fsm also a "server"? It seems like gen_fsm is used to manage a process that have multiple stages to fulfill its job, where gen_server by and large has only one state, is that correct? If not, what are the differences?
<br><br>* when should one use gen_fsm? and when should one use a gen_server? <br><br>* I've read that the best way to handle multiple requests is to use {noreply, State} in conjunction to spawn worker processes to handle the request - should the worker process also be gen_server or gen_fsm? For example, what should a web server's worker process be?
<br><br>* what's a good way to test the spawning to make it that it works? I mean, are there available tools to simplify the process?<br><br>Thanks very much,<br>yc<br><br><br><br><br><br><br><br>
