Hi all,

I just notice that in this page, browser support is IE7, but I just tried with IE9 and IE10 and I receive this error : 
 Object doesn't support property or method 'overrideMimeType' 

Thanks a lot.

Hello Marie, 
Thanks for reporting! 
I can confirm it doesn't work in IE8 either (the only version I was able to test).

The compat data which is displayed comes from a GitHub repo and more precisely from this file https://github.com/mdn/browser-compat-data/blob/master/api/XMLHttpRequest.json#L1248
@ Marie: do you feel comfortable making a pull request for this file in order to fix this issue?
I can help in the process if needed. If you don't want to, please tell so that I can go ahead.

Again, thanks for your contribution.

Thanks for your answer Julien. 
Here browser support is IE11 https://msdn.microsoft.com/en-us/kb/dn448456(v=vs.80), do you want me to fix the issue with this version ? 

No problem for the PR, it will be my pleasure to do it. Should be done by tomorrow :)

Thanks!

Yes IE11 is right. I've done more tests with the different compatibility modes of IE and this confirms the MSDN doc.

Thanks! :)

I think this can be closed now as the PR got merged.
The change won't be applied immediately as stated in https://github.com/mdn/browser-compat-data/pull/1792#pullrequestreview-112709785 but we can "VERIFIED" this bug when it'll be done :)
