/**
* Apply IE 8 and 9's cross domain support if needed and available.
*
* XDR enabled cross-origin requests, but with sever restrictions. Please
* understand these restrictions before using this interceptor. For example:
* only GET and POST are supported, there is no response status code, there
* are no request or response headers except for the response Content-Type,
* the remote server must use the same scheme as the origin http-to-http
* https-to-https.
*
* http://blogs.msdn.com/b/ieinternals/archive/2010/05/13/xdomainrequest-restrictions-limitations-and-workarounds.aspx
*
* If needed, this interceptor should be installed as close to the
* interceptor chain root as possible. When the XDR client is needed, any
* other interceptors in the primary chain are skipped. It is possible to
* mimick the primary interceptor chain, by wrapping the XDR client in the
* same interceptors and providing the resulting client as the 'xdrClient'
* config property.
*
* @param {Client} [client] client to wrap
* @param {Client} [config.xdrClient] the client to use when XDR is needed, defaults to 'rest/client/xdr'
*
* @returns {Client}
