From within an app, it appears I need to change a proxy to use the GET method to read data and not the OPTIONS method. I have attempted to set the 'method' for the proxy but it does not appear to be taking effect.
var operation = new Ext.data.Operation({
action: 'read',
});
var proxy = new Ext.data.proxy.Ajax({
type: 'ajax',
url: testURL,
method: 'GET',
withCredentials: true
});
proxy.read( operation );
Request Headers from debugger (notice OPTIONS)

The following code works but is not independent of a data store:
var createCORSRequest = function(method, url) {
var xhr = new XMLHttpRequest();
if ("withCredentials" in xhr) {
// Most browsers.
xhr.open(method, url, true);
} else if (typeof XDomainRequest != "undefined") {
// IE8 & IE9
xhr = new XDomainRequest();
xhr.open(method, url);
} else {
// CORS not supported.
xhr = null;
}
return xhr;
};
var url = testURL;
var method = 'GET';
var xhr = createCORSRequest(method, url);
xhr.onload = function() {
// Success code goes here.
alert( xhr.response );
};
xhr.onerror = function() {
// Error code goes here.
};
xhr.withCredentials = true;
xhr.send();
