I cannot get jquery's ajaxSend (http://api.jquery.com/ajaxSend/) to properly modify the parameters. I have:

$(document).ajaxSend(function(event, request, settings) {
    settings.data = $.deparam(settings.data);
    settings.data['random'] = new Date().getTime();
    settings.data['_method'] = 'get';
    settings.data = $.param(settings.data)
    $.log(settings);
});


$(document).ready(function() {
    //...snip...
    $.ajaxSetup({
        data : {
            remote : 1,
            authenticity_token : encodeURIComponent(AUTH_TOKEN)
        }
    });
});

The idea here is that we always want 4 param sent across: remote and auth_token always get set properly. However, random and _method (both needed for IE issues) do not get set. Logging settings inside ajaxSend shows me that they are set to settings.data:

"remote=1&authenticity_token=6GA9R_snip_253D&random=1270584905846&_method=get"

but when it gets sent across the wire, I only have the following:

  authenticity_token 6GA9R_snip_253D
  remote 1

Why in the world is this not working?
