Having been a stupid user myself for years I would like to prevent those using the flash video recorder I’m working on from having an opportunity to make the kind of mistake I know I would have made a year ago.

I have a tutorial video on my web site that demonstrates how to use the recorder BUT I know many won’t take the time to watch it. Probably the most important point I make in the tutorial is to instruct them to click “LogOff” to disconnect from the rtmp server when they have finished making a recording. If they don’t, the session on the server won’t terminate properly. So this is more of a design concept question.

I think I should add an “ExternalInterface.addCallback” to the SWF and a javascript function to my HTML page that will send a call to the routine in the SWF that handles connecting and disconnecting from the server. I think I can attach that function to the “Submit Button” of a form on the web page.

Questions:

1.Is this a sound approach or is there a better one?

1. Can I add the call for the javascript function to the ACTION element of the form and then have it call my php mail routine after the disconnect?

2. In the example I found on Adobe’s web Site the AS2 code sends a return to the javascript function. I don’t see a need to do that. is it required?

Any insight will help me keep from shooting myself in the foot.
