     NSArray *paths = 
     NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

     NSString *documentsDirectory = [paths objectAtIndex:0];

     NSString *saveLocation = 
     [documentsDirectory stringByAppendingString:@"myfile.zip"];

                  timeoutInterval:60.0];    

     NSData *received = 
     [NSURLConnection sendSynchronousRequest:theRequest
