This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
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 (
hsdnsreturns 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.
