This page is truly a dynamic web page that "calls" a "web service" from the http server and uses the result of the call to update (not replace) this page. Below is an HTML Form that use JavaScript's XMLHttpRequest
object to send two parameters to the http server which passes those two parameters to a process (running on the server) that computes a result that is returned to this client and used to update just part of this web page. The technique of using XMLHttpRequest
to update part of a web page is often called Ajax.
Be sure to watch the http traffic using some version of "Live HTTP Headers".
