unablle to download the tar file

I would like to have a look at the opensource darwin code.But i am unable to download the tar file from my mac(thru IE and safari)After i enter the username and password the screen gets refreshed.

The same casn be done thru my XP.Any one have a clue about this???

I assume your trying to download off the ADC (apple developer connection) that site is a tricky one, and sometimes they just reject you for fun it seems. If you right click and click download link to disk that should do it... but I think they get redirects.
