Produce a copy of a string in which the characters + % = ; and control characters are replaced with %hh . This is a gentle form of URL encoding attempting to cause as little distortion to the string as possible . The characters = and ; are meta characters in cookies . By convention they are escaped using the URL - encoding . This is only a convention not a standard . Often cookies are expected to have encoded values . We encode = and ; because we must . We encode % and + because they are meta characters in URL encoding .
