How to get window onbeforeload to always run?

Question

I have a static dictionary style counter that decrements when a user leaves a page. I can hit F5 or Crtl-F5 in a browser like Firefox and it Decrements fine.

However, if I spam crtl-F5 then the decrement operation does not take place. Maybe the page is refreshing faster than the javascript can load.

Is there any way around this? The code below runs when a user leaves the page.

I should mention that I am incrementing in the page_load event (asp.net)

 // decrement
window.onbeforeunload = confirmExit;
function confirmExit() {
    var request = {
        "channelId": channelId
    };

    // needed for ie7
    var params = $.toJSON(request);

    $.ajax({
        type: "POST",
        url: "Live.aspx/Decrement",
        data: params,
        contentType: "application/json; charset=utf-8",
        dataType: "json"           
    });
}

you should force that request to be syncronized, `async: false` — jAndy, Jan 20 '12 at 18:49
@chobo: well I don't know how "hard" you spam, but this code should be at the very top of your html document. So basically ``. — jAndy, Jan 20 '12 at 19:06
The page gets incremented before the html is even displayed, so that doesn't work — chobo, Jan 20 '12 at 19:21
Maybe try doing it the "jQuery" way? http://stackoverflow.com/questions/1889404/jquery-ui-dialog-onbeforeunload#answer-1889450 — blong, Jan 20 '12 at 22:05
Yup, I have to increment and decrement in Jquery and it works — chobo, Jan 20 '12 at 23:10
