[Pharo-users] Strange results from Zinc for the www.delicious.com domain

I have just come across a very odd 'bug'? in Zinc. Evaluating the two lines (below) will return the same result for the various domains I tested, but not for Delicious. In their case, the HTTPClient returns what I expected - i.e. the contents of the page. But, the Zinc client returns an undefined object. Any thoughts on what is going on - user agent maybe?? response := HTTPClient httpGet:'http://www.delicious.com'. response2 := ZnHttpClient new url:'http://www.delicious.com'; get. Cheers Andy
