Submitting forms vs. a browser requests

[toionbon]

If you put a URL into your browser with a query string attached, you're submitting a GET HTTP request to that page, and the page then comes down into your browser. If you have page that submits a form using GET to some action item page that will process the form, you also submit a GET HTTP request to that action item page, but the action item page doesn't come down into your browser. The processing of the form may be totally silent, perhaps just putting your QueryString variables into a database.

My question is, what is the basic difference here? What makes the browser request connect to the calling browser and display any Response.Write() text, etc, and then download the page, while the form HTTP request doesn't seem to connect at all to the calling browser?

Thanks for shedding any light on this issue.
