In limited situations OkHttp will retry a route if connecting fails:

 * When making an HTTPS connection through an HTTP proxy, the proxy may issue an authentication challenge. OkHttp will call the proxy [authenticator](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-authenticator/) and try again.

 * Fix: Drop `Content-Length` header when redirected from POST to GET.
 * Fix: Correctly read cached header entries with malformed header names.
 * Fix: Do not directly support any authentication schemes other than "Basic".
 * Fix: Respect read timeouts on recycled connections.
 * Fix: Transmit multiple cookie values as a single header with delimiter.

A single HTTP call may require follow-up requests to be made to handle authentication challenges, redirects, and HTTP-layer timeouts. In such cases multiple connections, requests, and responses may be attempted. Follow-ups are another reason a single call may trigger multiple events of the same type.
