IE8 Beta 2 and XDomainRequest (XDR)
If anyone else is struggling trying to get XDR working on IE8 Beta 2 (as I have been) note that the server no longer has to respond with the header:
XDomainRequestAllowed: 1
but instead should add the following header:
Access-Control-Allow-Origin: *
You can do this in ASP.NET with the following line of code:
context.Response.AppendHeader("Access-Control-Allow-Origin", "*" );
More details on the IE blog here.
