open fun connectStart(call: Call, inetSocketAddress: InetSocketAddress, proxy: Proxy): Unit
Invoked just prior to initiating a socket connection.
This method will be invoked if no existing connection in the ConnectionPool can be reused.
This can be invoked more than 1 time for a single Call. For example, if the response to the Call.request is a redirect to a different address, or a connection is retried.
