    Load balancing issues with Umbraco 7

    Hi there,

    I don't know if anyone can help me with this one but I'm having an issue with umbraco 7 and a solution with load balancer.

    Currently my A record is pointing to the load balancer and as soon as I login I get the following error.

    Happy wonderful wednesday

    Session timed out. log in below

    I know that before in order to synchronise all files and folders you would have to set up the distributedCall but this is not even a content issue is to do with the session.

    P.S. love the message.

    Regards,
    Pedro

    Well if anyone has the same problem as I did here's my solution.

    After trying changing the sessionState and scrutinising every IIS configuration I got nowhere.

    The solution was to add a machine key to <system.web> in the web.config and that seemed to fix it.

    I'm guessing your load balancer wasn't session aware, so when you were making requests the server changed and the session could no longer be decrypted between servers. Changing the machine key makes the 2 servers encrypt it using the same key so the session is remembered.

    The recommended way of deploying load balanced servers is to use one server for the backend rather than going through the load balancer. Is your media on a NAS/SAN or CDN?
