skyview.request.SkyViewDetainter

public class SkyViewDetainter
extends Detainter

This class defines string patterns and rules that are used to do taint checking for Skyview CGI calls. A hash map of acceptable character patterns is created upon construction and are matched against user input associated with each CGI parameter. If the pattern for a CGI parameter is not found the input is checked for characters that are not allowed. Some parameters such as survey name are checked against a pattern of allowed characters and then checked again to make sure certain sequences of allowed characters are not present.
