  // setting up the request object now
  request = [[NSMutableURLRequest alloc] init];
  [request setURL:[NSURL URLWithString:urlString]];
  [request setHTTPMethod:@"POST"];
  
  /*
   add some header info now
   we always need a boundary when we post a file
   also we need to set the content type
  
   You might want to generate a random boundary.. this is just the same
   as my output from wireshark on a valid html post
   */
  NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
  NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
  [request addValue:contentType forHTTPHeaderField: @"Content-Type"];
  
  /*
   now lets create the body of the post
   */
  NSMutableData *body = [NSMutableData data];
  [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
  [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"ipodfile.jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
