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: http://tc.labs.opera.com/apis/XMLHttpRequest/open/015.htm (I hope the above is relatively clear. Feel free to ask questions.) -- Anne van Kesteren <http://annevankesteren.nl/> <http://www.opera.com/>
