Introduction:

Why I am getting this exception? What is the cause of this error. Developers are always curious to know the root cause of an exception, even though they found the solution from elsewhere. So what is the reason of this exception (400 Bad Request).The answer is security. Security is an important feature for any application. ASP.NET try to his best to give you more secure application environment as possible. One important security feature is related to URLs. Because there are various ways a hacker can try to access server resource. Therefore it is important to make your application as secure as possible. Fortunately, ASP.NET provides this security by throwing an exception of Bad Request whenever he feels. In this Article I am try to present when ASP.NET feels to throw this exception. You will also see some new ASP.NET 4 features which gives developers some control on this situation.
