1.Why does only one copy of a servlet object get created? What happens if you want to remove an old servlet object currently running but do not want to stop the entire servlet engine? 2.How does one servlet object deal with interactions from many browser? (e.g. if your servlet ran an email site, how can it keep track of hundreds of users logging in, reading their mail, etc.)
