[jira] [Created] (HTTPCLIENT-2178) Implement Happy Eyeballs V2 (RFC 8305)

Ryan Schmitt created HTTPCLIENT-2178:
----------------------------------------

             Summary: Implement Happy Eyeballs V2 (RFC 8305)
                 Key: HTTPCLIENT-2178
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2178
             Project: HttpComponents HttpClient
          Issue Type: Wish
          Components: HttpClient (async)
            Reporter: Ryan Schmitt


When a hostname resolves to multiple IP addresses, the Happy Eyeballs algorithm for connection establishment uses multiple async connection attempts in order to establish a working connection more quickly. This is essentially a faster version of the logic in {{MultihomeSocketConnector}}. Among other benefits, it solves the issues with IPv6 brokenness that can occur when a hostname resolves to both IPv4 and IPv6 addresses.
