Is there a way to know which key has been pressed while sending request to a servlet.
Like GO,REFRESH or BACKSPACE (especially the BACKSPACE).

Sitaram,
No. You only know that the request has been submitted.

You can identify a backspace/reload case by putting a value in the session when the page is first loaded and seeing if it is already there. This is the "token" approach.
 
Don't get me started about those stupid light bulbs.
