ASP.NET request validation causes: is there a list?

Question

is anybody aware of a list of exactly what triggers ASP.NET\'s HttpRequestValidationException? [This is behind the common error: \"A potentially dangerous Request.Form value

Answer 1

From MSDN:

'The exception that is thrown when a potentially malicious input string is received from the client as part of the request data. '

Many times this happens when JavaScript changes the values of a server side control in a way that causes the ViewState to not agree with the posted data.
