负载平衡环境中的ASP.net状态服务器丢失会话

Question

I am aware that this is a commonly asked question but I have yet to find anything that answers my question. I am randomly losing session data in a load balanced environment. I have done the following:

• Set all the servers to the same state server
• Ensured that all the machineKeys in the web.config are the same
• Ensured that all the machineKeys in the machine.config are the same
• Ensured that all the paths to the web service files are the same (case sensitive)
• Made sure that the services all have the same ID

The session simply will not persist over multiple web servers. The following is the web.config session information:

    <sessionState cookieless="UseCookies" mode="StateServer" stateConnectionString="tcpip=[ipAddress]:42424" stateNetworkTimeout="30" timeout="60" />

Any ideas? I am out of them. Thanks!

I've been told it's not possible to persist session data in a multi-server environment unless you use a SQL Server instance to store it...I'm assuming you're familiar with it but here's a link for others who may not be:
