Rajkumar,

The essential difference between ASP and DHTML is that
DHTML, being run at the browser, is interactive with the user independent of the server or the source file.  DHTML, therefore, requires no network resources to provide its interactive functions.  ASP, being run on the server, is no different than SSI (server side include) or CGI programs in that the user input must be sent back to the server for processing.
