1 Introduction

This document describes the level of support provided by Microsoft web browsers for the Cross-Origin Resource Sharing [CORS] specification, published 16 January 2014. The [CORS] specification defines a mechanism to enable client-side cross-origin requests. It is a building block for other specifications, so-called CORS API specifications, which define how the [CORS] specification is used.

This document describes support for aspects of [CORS] pertinent to [XDomainRequest], images [HTML5:2014], and fonts [CSS-FontsLevel3].
