 If a class or servlet implements SingleThreadModel interface,it depends on the server which technology is implemented.

for server there r 2 options. .......1)Multiple Instances

                                            2) Request serialization

 if it(server) follows 1st choice,it creates multiple instances for each servlet and then processes the incoming requests.

if it follows 2nd choice,it creates single instacne for each servlet and then allows only one servlet to be get processed or handle requests. if more than one request came at once, it queues up requests or let them(requests) wait until earlier requests processed.
