tinyproxy used to do a full hostname resolution whenever a new client connection happened, which could cause very long delays (as reported in #198). there's only a single place/scenario that actually requires a hostname, and that is when an Allow/Deny rule exists for a hostname or domain, rather than a raw IP address. since it is very likely this feature is not very widely used, it makes absolute sense to only do the costly resolution when it is unavoidable.
