Error 302 in kCFErrorDomainCFNetwork maps to  
kCFErrorHTTPConnectionLost, which indicates that "The connection to  
the server was dropped. This usually indicates a highly overloaded

The underlying HTTP stack in Chrome is completely different than what  
is used in Safari's WebKit.  Safari's WebKit makes use of CFNetwork,  
but I'm not sure what exactly Chrome uses. If you have reproducible  
instances of this problem you should file bug reports against  
CFNetwork (<http://bugreport.apple.com/>) and Chrome (<http://code.google.com/p/chromium/issues/entry 
 >) so that they can be investigated by the respective teams.  Given  
that two different HTTP stacks are running into a similar issue it is  
quite possible that the problem is in fact a server-side issue where  
the server is prematurely dropping the connection.
