当我查看发送的内容时，我可以向在 fiddler 中可见的 ajax 调用添加注释吗？

Question

I have code like this:

        $.ajax({
            cache: false,
            url: "/xx"
        }).done(onAjaxDone).fail(function (jqXHR, textStatus, errorThrown) {
            Dialog.Alerts.ajaxOnFailure(jqXHR, textStatus, errorThrown);
        });

and

        $.ajax({
            cache: false,
            url: "/xxxxx"
        }).done(onAjaxDone).fail(function (jqXHR, textStatus, errorThrown) {
            Dialog.Alerts.ajaxOnFailure(jqXHR, textStatus, errorThrown);
        });

When I check with fiddler I notice more than one ajax call. Is there some way I can add some meta to the ajax calls that would not be used but that would allow me to see where the call is coming from in my code. Something like a comment that I could place within the ajax() and that would be visible going across the network?

You could send some meta-data in a non-standard header, using the headers option:

$.ajax({
    //...
    headers: { MyCustomHeader: "Location #1" }
});

Then check for it on the server side using Request.Headers["MyCustomHeader"] .

You could also append a key to the query string, but I suppose using an HTTP header is less invasive.
