```
public boolean isRotateEnabled(javax.servlet.http.HttpServletRequest request)
```
    Rotation in case of AJAX requests is not supported currently because of possible race conditions.
    A Single Page Application can fire multiple simultaneous requests. If rotation is enabled for AJAX requests, the first request could trigger a token change before the validation of the second request with the same token, causing false-positive CSRF intrusion exceptions.
    
    Parameters:
    
    request - the current request
    
    Returns:
    
    True if rotation is enabled and possible
  - onSessionCreated
```
public void onSessionCreated(LogicalSession logicalSession)
```
    Method to be called by a logical session implementation when a new session is created.
    
    Example: HttpSessionListener.sessionCreated(javax.servlet.http.HttpSessionEvent)
    
    Parameters:
    
    logicalSession - a logical session implementation
  - onSessionDestroyed
```
public void onSessionDestroyed(LogicalSession logicalSession)
```
    Method to be called by a logical session implementation when a session is destroyed.
    
    Example: HttpSessionListener.sessionDestroyed(javax.servlet.http.HttpSessionEvent)
    
    Parameters:
    
    logicalSession - a logical session implementation
  - writeLandingPage
```
public void writeLandingPage(javax.servlet.http.HttpServletResponse response,
                             String logicalSessionKey)
                      throws IOException
