If you want to be compatible with IE for this, what you should check
is what happens if the base URI is _changed_ while the XMLHttpRequest
object exists, e.g. by changing the attribute directly or by mutating
the <base> elements in the document (if that works).
I just tested this. Internet Explorer indeed takes note of of changes
to <base>. (Either changing .href or adding a <base> element.) Ouch!
I forgot to mention the testcases in my previous e-mail:
http://tc.labs.opera.com/apis/XMLHttpRequest/open/018.htm
http://tc.labs.opera.com/apis/XMLHttpRequest/open/019.htm
http://tc.labs.opera.com/apis/XMLHttpRequest/open/020.htm
Note that the pass conditions of none of the above should be considered
stable. The testcases will change over time to reflect the latest
version of the Working Draft. They are just to aid in decisions on
moving forward at the moment.
I added the following testcases based on suggestions from Björn (thanks!):
http://tc.labs.opera.com/apis/XMLHttpRequest/open/021.htm
http://tc.labs.opera.com/apis/XMLHttpRequest/open/022.htm
http://tc.labs.opera.com/apis/XMLHttpRequest/open/023.htm
I also modified some of the earlier mentioned testcases (flush your cache)
to reflect what Internet Explorer implements. The moment you invoke the
open() method Internet Explorer resolves the URI and stores it as part of
the object. Changing it after open() has no effect on the fetched URI.
I suppose the draft should say that you store a reference to the baseURI
attribute instead of storing the value. The only problem with that is what
when the iframe is removed you can't directly remove the window object.
Other testcases have demonstrated that in such cases you still use the
baseURI from that Window if you used the XMLHttpRequest attribute from
that Window as constructor:

(I hope the above is relatively clear. Feel free to ask questions.)
