lF itself has no HTTP support. You can use WOHTTPConnection,  
WORequest, WOResponse.

Convention is to use lowercase names for variables, eg:
   urlString

For escaping you can find NSString methods in NGExtensions (those work  
on all Foundations).

Because your escaping code is b0rked. You escape almost the whole URL:

  URLString = [URLString stringByEscapingURL];
  URLString = [@"http://" stringByAppendingString:URLString];

How is that supposed to work? (you put everything in the hostname ...)

You always need to escape the components of an URL individually. This  
is also true for the path, btw (escaping the whole path will escape  
the '/', hence, it will result in a single resource name!).
