Readme

Caching asynchronous DNS resolver built on top of GNU ADNS http://www.chiark.greenend.org.uk/~ian/adns/.

  • Resolves several IP addresses for one host (if available) in round-robin fashion.

  • Throttles number of parallel requests (so DNS resolving continues to work even under heavy load).

  • Errors are cached too (for one minute).

  • Handles CNAMEs (hsdns returns error for them).

This cache is tested in a long running web-crawler (used in https://bazqux.com) so it should be safe to use it in real world applications.
