                                         java.lang.String defaultValue,
                                         boolean isZeroLengthValid)
        Searches for the asked parameter on the request object.
        Parameters:
        rk - RequestKeys object initialized
        param - String containing the name of the parameter to search for
        defaultValue - String with the default value of the parameter
        isZeroLengthValid - Boolean flag indicating if the value of the parameter can be zero-length
        Returns:
        the value of the parameter. If not found, or the length of the value is zero and this is not allowed, the default value will be used. Otherwise, the value found for the parameter will be the output of the method.
