Cross Domain requests in IE are supported via only the IE-specific object called XDomainRequest. XDomainRequest is too basic when compared with the XMLHTTPRequest object that’s implemented in all other major browsers!
I am guessing you are using jQuery for Ajax-requests. jQuery does not use the XDomainRequest for making Cross-Domain calls on IE, so you are out of luck!
XDomainRequest offers only a subset of XMLHTTPRequest’s features. For example, it is impossible to insert any custom headers to the HTTP-Get/Post requests, via XDomainRequest [typically you would use the jQuery’s “onBeforeSend” callback for this purpose].

I encountered all these in my current project and finally ended up using a Proxy i.e. mod_proxy, on the Apache server that’s hosting my app. Please have a look at my related answer on this topic How to make an ajax request to an API using CORS and backbonejs
