the destory method is not call by browser, it is called by servlet
engine, when servlet engine "think" this servlet should be destroied,
it will call the servlet's destroy method.

maybe you should have a look on servlet engine's whitepaper.

please tye this: ~~~~
sent a doget require to your servlet, (you see the return
page), then delete the .class file, sent another require to the
servlet,you will find the page is there still.
