http://twitter.com/statuses/user_timeline/adaptuqa.json?count=5&rand=8942 and basic authentication popup

[Vijay]

Hi,

I am trying to use this http://twitter.com/statuses/user_timeline/adaptuqa.json?count=5&rand=8942
for getting statuses from my twitter web app and I keep getting this
Basic Authentication popup to enter my userid/pwd.I can type in the
url http://twitter.com/statuses/user_timeline/adaptuqa.json?count=5&rand=8942
and it lets me access my statuses though in the browser(IE or Chrome).

How can I avoid this basic auth popup showing up for the public twees
from the adaptuqa a/c from my webapp ? I am using jquery with a $.ajax
call to the URL above. I am trying to access it from behind a proxy
firewall.

TIA,
Vijay
