$http empty response body for IE9

[bvaughn]

This issue is occurring for Angular 1.2.10 and seems to still exist in Git. It is related to #4738 and #4464. Supposedly the above defects were fixed with commit 509ec74 but the fix isn't working as expected in IE9.

The IE debugger shows that the XHR object defines a response attribute but it is null. The response body is contained within a responseText attribute.

So perhaps a better fix for this would be to change httpBackend line 94 from this:

response = ('response' in xhr) ? xhr.response : xhr.responseText;

To something more like this:

response = ('responseText' in xhr) ? xhr.responseText : xhr.response;

Thanks for the bug report @bvaughn ! Could you please create a plunkr which illustrates the issue? Thanks.

[bvaughn]

Sure thing! Working on that and a pull request too.

[davidjnelson]

Awesome, thanks @bvaughn !! :-)

@davidjnelson After digging in further I've discovered that this problem is actually being caused by a non-standard response coming back from our service endpoint. My apologies! Going to close this as invalid.

[bvaughn]

For information's sake, it looks like the cause of this issue is our use of the xdomain lib and a proxy.html on our service endpoint that initializes both response and responseText.

@davidjnelson I am actually a little curious why the httpBackend implementation was changed from version 1.2.3. That version did what I wish the newer version does. :)

response = xhr.responseType ? xhr.response : xhr.responseText;

Edit: I'm guessing it's because it's easier to check for 'response' than to check for 'responseText' or 'responseXML'*.
