HTTP exception using SampleXML provider

Question

I tried using http:// to download xml feed from a content provider and it returns FileNotFoundException as follows.
While trying to resolving the URL in netscape(ver 4.78) i get a SaveAs dialog to save the xml feed. The portal works fine when i use file:// to access the xml feed from the disk. As suggested in the forum proxy settings in our network looks ok.
I like to have dynamic download capablity for xml feed.
Any suggestions please.

Thanks for your interest. I did download 'wget' and i got the xml feed saved in a file '@service=headlines' (no extension)
I assume XMLProvider does use the data packets on the fly from the http:// site; instead referring to some persistent xml file. If XMLProvider does refer to persistent data, i'm not sure how will it recognise this file ?
Thanks.
