Have a look to this code snippet:-
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[webData
You're not getting any error messages in didFailWithError either? Kind of a silly suggestion, but are you sure you're setting the proper NSURLConnection delegate?
NSURLConnection* connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
Sometimes it's something small like that.
Another idea is to drop in a toolkit like ASIHTTPRequest and see if it works going through them.
