Every link clicked or form submitted generates a different request that triggers a CGI script; the script starts, reads its parameters, do its task, and exits. There is no "long running process" in CGI - the whole "world" must be recreated on each request (a total waste of resources, sure). If processing takes so much time, it's better to assign it a "ticket" - the user may come back later and see if its "ticket" has been finished, or the system may send an email telling him. -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
