This class will generate GET or POST headers for you - very quickly and without the speed decrease of concatenating strings - there is absolutely no concatenation in this class.
StringBuilder and string.Format have both been proven to be faster than concatenation, and when you're generating headers, you need this speed.

var requestHeaders = headerGenerator.CreateGETHeaders("/index.phtml", "www.neopets.com", "http://www.google.co.uk", "*custom user agent*", false, "");
Oh - I tested this with a StopWatch() in C# - and it came back with a timing of 0 milliseconds. I assume I've broken into the microsecond barrier here, so you can guess that it's pretty fast
