[Source] Java uses OkHttp to send HTTP network requests

OkHttp is a default efficient HTTP client:

  • HTTP/2 support allows one socket to be shared for all requests from the same host.
  • Connection pooling reduces request latency if HTTP/2 is not available.
  • Transparent GZIP reduces download size.
  • Response caching completely avoids network duplicate requests.


OkHttp insists when there is a problem with the network: it silently recovers from common connection problems. If your service has multiple IP addresses, OkHttp will try an alternate address on the first connection failure. This is required for IPv4+IPv6 and services hosted in redundant data centers. OkHttp supports modern TLS features (TLS 1.3, ALPN, certificate locking). It can be configured to fall back for a wide range of connections.
