Can someone exlpain to me what happens internally when I hit the STOP button while the browser is downloading a page.

Does the browser stop downloading the page and also tell the server anything in order to stop sending more packets. What happens to the TCP connection bet the browser and the server ?

Is there a way to get the server stop the CGI process runngina s result of an HTTP request when the user hits the browser STOP button ?

Yes, stop actually stops the page from loading. Well, it is supposed to. Often, IE at startup will not acknowledge. Also, running scripts can interfere with anything on toolbar, including 'stop'. But proper anser is yes, it stops, that is purpose. Any program interfering with this is violating the rules and making this all even more confusing.

Once you have connection/session, the stop button will not end it or log you off. All it does is keep you from having to suffer a tremendously long download of an overly-complicated web_page_view. It is unrelated to passwords or SSL.

There is no way any user can count on stopping processes on the server side. This can be done, of course, for specific application. But once cgi kicks off on server, it can run, chain, split, fork, thread, and go who knows where, beyond user control. And actually, that is its purpose. CGI is for running things independent of user. Turn your machine off, and it may still be running.

Very interesting stuff.  Curious if Browser type and version wouldn't also impact the results.  Thinking about IE versions with known memory leaks, as an example, such as IE 5.5 which was fixed by Service Patch 1 (highly recommended).  Here's what I think may apply and why:

Memory Leak in Internet Explorer Default Download Behavior
Every time you use the Startdownload method for downloading, the memory that is used by Iexplore.exe increases. You can observe this memory leak by using Performance Monitor to monitor the Private Bytes count for Iexplore.exe.

Internet Explorer does not release the heap memory that is used by the Startdownload method.

IE 5.5, even with SP2 had some odd issues, all of which I experienced to have been resolved once I upgraded to the final release of IE version 6 from here:

I, personally, enjoy using IE plugin viewers to see and do things as in the past with my personally customized version of this browser.  So I found that IE 5.5 caused a problem with a number of my plugins, so after upgrading to IE 6.0, I found that updating my Viewers as follows, including the Adobe viewer which I need for some images and interfaces, as well as the updated version of Quicktime (version 5), all my previous plug in support worked better than before ... and I've had improved performance in general.

Hopefully this will serve you as well.

Adobe SVG Viewer link where you can download if needed, or test to see if installed:

Quicktime 5

Best of luck, let us know.
