# 3699 Cross Origin Requests Not Being Handled Properly by the Web Server for DataSets and Static Content

---

When I use cross site scripting to Load data tables, it works with IE but not with Chrome or Firefox.

The reason is because IE doesn't care and just does it, but Chrome will send an "Access-Control-Allow-Origin" header before passing the actual request. This header is added automatically by Chrome because it has detected cross site scriting.

I modified my web server to return a confirmation to the "Access-Control-Allow-Origin" message to confirm that it was in fact allowed, but EWB sees some kind of response to this "allow" message that is not what it was expecting and throws a data response error.

I am unsure why sending a header response to confirm access control returns data to EWB, but it does appear to and this is what cause the problem.
