        Description copied from interface: ParamParent
        Adds a parameter to this tag's URL. The intent is that the <param> subtag will call this to register URL parameters. Assumes that 'name' and 'value' are appropriately encoded and do not contain any meaningful metacharacters; in order words, escaping is the responsibility of the caller.

      • stripSession

        public static String stripSession​(String url)
        Strips a servlet session ID from url. The session ID is encoded as a URL "path parameter" beginning with "jsessionid=". We thus remove anything we find between ";jsessionid=" (inclusive) and either EOS or a subsequent ';' (exclusive).
