I have exactly the same problem as Florian - web service does not get called unless I put an ‘alert’ at the end of the onunload handler. Anyone got any leads here?

Good article.
Asynchronous calls reach server for IE (I have no need for retrieving response) but have problems with Firefox(Suppose problems may exist with other browsers too). So using Synchronous calls in onUnload event solved problem.
Easy way for making Sync calls is to pass false as the third parameter in the AJAX.open method and no need to set up an onreadystatechange handler.

Thanks for the great tutorial. When using it locally, how can I capture the fact that the user is logged in. I added your sample code to a controller and the filter chain continuously kicks me out. Thanks for the help.

Hi there,

I’m coding an ASP.net website and the synchronous solution doesn’t solve my problem : the webservice method that I call isn’t triggered everytime… (IE / FF)

It’s very strange because it perfectly works when I display an alert box at the end of the handler

Any idea ?
