      Description

      1674        HttpTransact::OSDNSLookup(State *s)
      1675	{
      1676	  static int max_dns_lookups = 3 + s->http_config_param->num_url_expansions;
      1677	  ++s->dns_info.attempts;
      

      The max_dns_lookups include :

      • 1 for origin domain, for example: oknet
      • 1 for default expansion, for example: www.oknet.com
      • n for url_expansions_string list, for example: oknet.org, oknet.net

      Thus, max_dns_lookups should be ```2 + s->http_config_param->num_url_expansions```

      6617	  static int last_expansion  = max_dns_lookups - 2;
      

      In the HttpTransact::try_to_expand_host_name, it is correct.
