TLS Settings #81
Comments
Hello, you can apply TLS specifications to a session using session.GetClientHelloSpec here is an example: session := azuretls.NewSession()
defer session.Close()
session.GetClientHelloSpec = func() *tls.ClientHelloSpec {
return &tls.ClientHelloSpec{

Any way to set the TLS Settings differently in a session, for example ciphers
