PUT request to Cross Domain URL fails only in IE

Question

I want to do a PUT request across a different domain. But the script fails only in IE.

I figured out what the problem was, in IE if you look at Internet Options > Security tab > Custom level > Miscellaneous > Access data sources across domains option was set to disable. The only way I was able to get my put request work is setting that option to Allow.

So my question: Is there a way I can get this working without enforcing end users to set the option?

There is XDomainRequest() which can be used for XDomain requests in IE but, this method doesn't support PUT.

Answer 1

IE9 and older does not support PUT method in cross domain request. Only GET and POST.

Answer 2

You could use a library like Xdomain or EasyXDM to get a CORS alternative using the Post Message hack.

I prefer to use Xdomain because it hijacks the native XMLHTTPRequest and provides a "drop-in" solution. EasyXDM forces you to use their API which means more conditional coding overhead, however, it supports IE6/IE7.

The main take away? Don't stop supporting CORS! Just make IE behave itself and opt-in to the future.
