There was a problem hiding this comment.
Paranoia... because I've been burned by this bugs too many times.
The root of the issue is: I don't know how browsers implement XMLHttpRequest.getResponseHeader.
Suppose I just did:
return {
get: responseObj.getResponseHeader
}
but then they implemented it as something like this:
XmlHttpRequest.prototype.getResponseHeader = function(header) {
var headers = this.parseResponseHeaders();
return headers[header];
}
When an adapter calls get, then this evaluates to our object--not the original XmlHttpRequest. Since we don't define parseResponseHeaders, it'd crash on an undefined function error.
I have no idea if this is a real risk... but the tl;dr is that this sucks. Since I can't eject it from the language, defensive binds keep the code safe.
