* This is essentially a generalization of the functionality that was implemented for SEC-399. Additionally, it will
* update the configured SessionRegistry if one is in use, thus preventing problems when used with Spring Security's
* concurrent session control.
* <p>
* If the response has already been committed when the filter checks the authentication state, then it isn't possible
* to create a new session and the filter will print a warning to that effect.
