   C{
       char *cache = VRT_GetHdr(sp, HDR_REQ, "\016cache-control:");
       char date[40];
       int max_age;
       int want_equals = 0;
       if(cache) {
	while(*cache != '\0') {
	  if (want_equals && *cache == '=') {
	    cache++;
	    max_age = strtoul(cache, 0, 0);
	    break;
	  }

	  if (*cache == 'm' && !memcmp(cache, "max-age", 7)) {
	    cache += 7;
	    want_equals = 1;
	    continue;
	  }
	  cache++;
	}
	if (max_age) {
	  TIM_format(TIM_real() + max_age, date);
	  VRT_SetHdr(sp, HDR_RESP, "\010Expires:", date, vrt_magic_string_end);
	}
