All Implemented Interfaces:

javax.servlet.Filter

public class RequestPathFilter
extends Object

Reject any request with an invalid path (i.e., HttpServletRequest.getPathInfo()).

The decoded request path must be a single-line string without any parent path segments ("../"). For more details, see validPath().

Note: Currently also rejecting strings that contain any less than ("<"), greater than (">"), or backslash ("\") characters. [May loosen this restriction later.]
