I am experimenting with long polling XMLHttp Requests (XHR) @
http://testbed.nicon.nl/slowload/longpoll.html. Having Avast antivirus (home edition) installed I noticed that its web shield effectively blocks the use of readyStates<4. Adding an exception for text/xml mime types in the web shield configuration solves this. But is there a way to solve this programmatically? I searched the net thouroughly, but didn't find solutions until now.
http://markmail.org/message/dvroivs45gonbto7 looked promising, but didn't work.
PS: I need the text/xml response to be able to read the response stream in Internet Explorer
