    • apply

      public String apply(String target, javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws IOException
      Description copied from class: PatternRule
      Apply the rule to the request
      Specified by:
      apply in class PatternRule
      Parameters:
      target - field to attempt match
      request - request object
      response - response object
      Returns:
      The target (possible updated)

    • applyURI

      public void applyURI(Request request, String oldURI, String newURI) throws IOException
      This method will add _query to the requests's queryString and also combine it with existing queryStrings in the request. However it won't take care for duplicate. E.g. if request.getQueryString contains a parameter param1 = true and _query will contain param1=false the result will be param1=true&param1=false. To cover this use case some more complex pattern matching is necessary. We can implement this if there's use cases.
      Specified by:
      applyURI in interface Rule.ApplyURI
      Parameters:
      request - the request
      oldURI - the old URI
      newURI - the new URI
      Throws:
      IOException - if unable to apply the URI
    • toString

      public String toString()
      Returns the replacement string.
      Overrides:
      toString in class PatternRule
