I posted this twice. But there was no satisfactory answers.

Here's what i tried using exception handlers. but it does not work
IF (cou > 0) THEN
          DECLARE
                l_url            VARCHAR2(256) ;
                l_http_request   UTL_HTTP.req;
                l_http_response  UTL_HTTP.resp;
                    l_url := hostname;
                    UTL_HTTP.set_transfer_timeout(5);
                        l_http_request  := UTL_HTTP.begin_request(l_url);
                     l_http_response := UTL_HTTP.get_response(l_http_request);
                  UTL_HTTP.end_response(l_http_response);
CASE WHEN l_http_response.status_code = 200  THEN
            proc('Success')
            WHEN l_http_response.status_code in(401,403,500,503) THEN
      proc('Error')
        END CASE;
                EXCEPTION WHEN OTHERS THEN
            Result := 'continue';
           END;
      END IF;
