    Description copied from interface: Valve
    Perform request processing as required by this Valve.
    
    An individual Valve MAY perform the following actions, in the specified order:
    - Examine and/or modify the properties of the specified Request and Response.
    - Examine the properties of the specified Request, completely generate the corresponding Response, and return control to the caller.
    - Examine the properties of the specified Request and Response, wrap either or both of these objects to supplement their functionality, and pass them on.
    - If the corresponding Response was not generated (and control was not returned, call the next Valve in the pipeline (if there is one) by executing context.invokeNext().
    - Examine, but not modify, the properties of the resulting Response (which was created by a subsequently invoked Valve via a call to context.invokeNext()).
    A Valve MUST NOT do any of the following things:
    - Change request properties that have already been used to direct the flow of processing control for this request.
    - Create a completed Response AND pass this Request and Response on to the next Valve in the pipeline.
    - Consume bytes from the input stream associated with the Request, unless it is completely generating the response, or wrapping the request before passing it on.
    - Modify the HTTP headers included with the Response after the invokeNext() method has returned.
    - Perform any actions on the output stream associated with the specified Response after the invokeNext() method has returned.
    Specified by:
    
    invoke in interface Valve
    
    Specified by:
    
    invoke in class AbstractValve
    
    Parameters:
    pipelineData - The run-time information, including the servlet request and response we are processing.
    context - The valve context used to invoke the next valve in the current processing pipeline
    
    Throws:
    
    IOException - Thrown by a subsequent Valve.
    
    TurbineException - Thrown by a subsequent Valve.
