    No. Not unless you're on the same local subnet. MAC addresses are a
    part of Layer 2 (Data Link). Once you are past the first router, L2
    information is dropped. Layer 3 (IP) is what is used for routing
    packets around.

    Subject: MAC address

    Guys,

    Lets say i am a web programmer and i want to use strong sessions.

    Is it possible for the web server to determine the MAC of clients
    browsing
    the application.

    If yes, I can programatically use this MAC address in sessions to
    prevent
    lot of session related attacks.

    For right now, say I can implement the web application in any language i
    want.

    Thanks
    -n
