Ext.Ajax.request POST request cache-buster

[lrobins]

Is it possible to makek an ajax request with method POST and have it apply the querystring _dc= to make it random so the calls won't be cached? If I make the call using Ext.Ajax.request it does not work with POST, by default it does work for a GET. Also, if the call is made through the proxy of a store, it adds the querystring _dc= to prevent caching.

Ext.Ajax.request({
    method : 'POST',
    url    : 'somewhere/over/the/rainbow'
});

That for me is having the _dc in the query string

Ext.Ajax.request({
            headers: {
                'Content-Type': 'application/json; charset=utf-8'
            },
            method: 'POST',
            params: Ext.JSON.encode({
                userId: getCookie('id')
            }),
            url: 'services/System.svc/MyMethodCall',
            scope: this,
            success: function (response) {
                //blah
            },
            failure: function () { //blah }
        });

When I run that code I don't get the _dc cache buster on the querystring, do the other properties I set cause it to function differently from your code?

I see it when I use your code.

I'm using touch 2.0, any idea what could cause the difference?
