Overwrite this method to fill your response.

Parameters:

aRequestScope - The request scope to use. There is no direct access to the HttpServletResponse. Everything must be handled with the unified response! Never null.

aUnifiedResponse - The response object to be filled. Never null.

Returns:

If EContinue.BREAK is returned, the content of the unified response is rendered to the HTTP servlet response and the filter chain stops. On EContinue.CONTINUE the content of the unified response is discarded and the filter chain continues as normal.

Throws:

IOException - In case of an error

javax.servlet.ServletException - In case of an error
