Hi,

I am trying to use the TLS package from hackage, and it works fine so far -- except when a client wants to do session resumption (note I am not an expert in TLS, so it might be something quite simple). In that case, I get an alert, "unexpected message", during handshake.
The handshake goes like this: ClientHello (with a SessionID) ServerHello (with the same SessionID) ServerHelloDone
Not an expert either, but section 7.4 of the TLS 1.2 spec (rfc 5246) does seem to say that this ServerHelloDone should be a Finished message instead.
and then the server says (AlertLevel_Fatal,UnexpectedMessage)
Do you mean that the client says this? If so, this may obviously be correct if the server sends the wrong message. Pehaps you can test with a different server implementation?
I'm not sure whether the "ServerHelloDone" should happen when resuming. Does anyone have a hint what may be going wrong? I am using TLS10 and the tls package with version 0.9.6.
Bye Dominique
