If using the underlying default <tt>SessionValidationScheduler</tt> (that is, the
{@link #setSessionValidationScheduler(SessionValidationScheduler) setSessionValidationScheduler} method is
never called) , this method allows one to specify how
frequently session should be validated (to check for orphans). The default value is
{@link #DEFAULT_SESSION_VALIDATION_INTERVAL}.

If you override the default scheduler, it is assumed that overriding instance 'knows' how often to
validate sessions, and this attribute will be ignored.

Unless this method is called, the default value is {@link #DEFAULT_SESSION_VALIDATION_INTERVAL}.
@param sessionValidationInterval the time in milliseconds between checking for valid sessions to reap orphans.
