should give the system a chance to encode the URLs.
  Regular URLs 
String originalURL = someRelativeOrAbsoluteURL;
String encodedURL = response.encodeURL(originalURL);
out.println("...");
  Redirect URLs 
String originalURL = someURL; // Relative URL OK in 2.2
String encodedURL = response.encodeRedirectURL(originalURL);
response.sendRedirect(encodedURL);
