ASP Security Functions v1.4 Updated

UPDATED: Added an SQL injection prevention method, Added more documentation, and a few more minor changes. This code will show you how to prevent header injection, the method GET (only allow POST from a form), unauthorized domain access, and invalid agent access. You see a lot of SQL injection prevention methods and what not, but nothing to this level. This is a first on PSC I belive. If you like it please leave some feedback and vote.
