I am trying to get external RSS feeds (CNN particularly) working on
MySites. I have enabled Kerberos and modified the web.config file with
the proxy information, but now I am getting this error message in the
RSS viewer:

ProtocolError occured trying to complete the request. The server
returned a status code of : BadRequest and the status description is :
"Bad Request ( The data is invalid. )"


The RSS viewer works fine with sharepoint driven RSS feeds (such as a
document library). But I can't seem to figure out why external feeds
will not work.
