    hi,
    I'm trying to understand the working of https. i started a packet capture(ssl) on wireshark and tried logging on to gmail and other sites which use https.

    In the traces, im not able to see the certificate sent by the server to my computer. the client hello message is immediately followed by the change cipher spec message from the server.
    the cipher spec = TLS_DHE_RSA_WITH_AES_256_CBC_SHA.

    i read somewhere that for certain ciphers, server certificate is optional :(
    please help where this is negotiated/ if this is a bug.

    thanks
