I have a flash application that needs to send a http request to the server which will disconnect the existing session immediately. I have a tried a few options but none is reliable. Option #1: On "onbeforeunload" event send a http request from inside the flash applications. Fallacy: This does not work because as soon as the browser is closed the flash player unloads the app and hence the communication breaks.
Option #2: On "onbeforeunload" event send a http request using XMLHTTPRequest in ajax. This works fine in IE but doesnt work in Firefox. When i debugged the http req in httpfox it threw "NS_BINDING_ABORTED" error which i think means that request was cancelled due to page unload.
Note that if i use an alert box, the requests are getting sent in both the options. But i cant use alert boxes. Is there any other way to do so ? or maybe kill the alert box after a timeout ?
