HtmlNet needs to support CORS in IE9: try XDomainRequest when XMLHttpRequest fails #53
Description
In order to issue cross origin XHRs in IE9, you must use XDomainRequest instead
of XMLHttpRequest. All other browsers let you just XMLHttpRequest.
Currently, HtmlNet uses XMLHttpRequest exclusively, which means that cross
origin requests will fail in IE.
We should either update HtmlNet to fall back to XDomainRequest, in the same way
that HtmlAssetManager already does --or-- just fix
