Thanks. That makes sense. I will take a look at the code.
I just wanted to make sure whether HttpInspect module
takes care of those scenarios when the HTTP header is
split across multiple segments (maybe due to a very long
cookie value). I know this condition is very rare but just
wanted to verify what HttpInspect would do in this case.
