Checks whether the token in th request is valid.
request - The servlet requestResets the token in the request
Main entry point, this method will check the request for the necessary TOKEN and if it is valid will call the passed closure.
For an invalid response an InvalidResponseHandler is returned which will invoke the closure passed to the handleInvalid method. The idea here is to allow code like:
withForm {
// handle valid form submission
}.invalidToken {
// handle invalid form submission
}
