velosurf.validation
Class ValidationFilter

java.lang.Object
  velosurf.validation.ValidationFilter

All Implemented Interfaces:

javax.servlet.Filter

public class ValidationFilter
extends java.lang.Object
implements javax.servlet.Filter

This class is an optional filter that will validate query data according to the "velosurf.entity" query parameter (may be multivalued). If data pass all validation constraints, the filter will let the request pass towards the form action. Otherwise, it will redirect back the user to the original form (using the referer query header). In this case, the filter will populate the session with the given values (escaped) so that they can be put in the form.
