Answer 1

I would suggest you to use Ext.data.JsonP.request instead of Ext.Ajax.request.

JSONP by definition from wiki

is a technique used by web developers to overcome the cross-domain restrictions imposed by browsers' same-origin policy that limits access to resources retrieved from origins other than the one the page was served by

Here is the documentation

Answer 2

I am sure you already know that JavaScript is case-sensitive; but did you know that Headers are, too?

The browser states correctly that Access-Control-Allow-Origin is not *, because Access-Control-Allow-Origin and access-control-allow-origin are two different headers - and only one of them is a valid CORS header.

Answer 3

We solved this issue:

• installed corsEverywhere firefox plugin to simulate an accepted cors so we could compare settings with/without simulation:

• Access-Control-Allow-Credentials true wasn't set at the server. ( cookie authentication )

• server ( Microsoft-IIS/7.5 ) didn't like * so we set remote site name explicit
• removed trailing / in sitename

works
