c# ASP.NET Session 变量未初始化或更新

Question

In my project, I'm trying to set the "userid" session variable, however for some reason the session won't initialise. This behaviour is for all session variables in any controller, except my base controller, which uses a different method to set session variables.

Currently, I've tried these ways to set the session variable:

Session.Add(...)
Session["keyname"] = "value";

I tried to initialise the session in Global.asax.cs , with some success, but these variables couldn't be updated:(

protected void Session_Start(Object sender, EventArgs e)
{            
    Session["userid"] = null;
    Session["name"] = null;
}

The normal session functionality in ASP.NET was working fine months ago, in this project, the code which uses the session variables hasn't been touched in weeks, and last worked flawlessly.

The web.config file has the current session configuration:

<sessionState mode="InProc" timeout="30" />
<pages enableSessionState="true"/>

I've tried everything I've read on this forum and others, but to no avail. I cannot regain "normal" session functionality. Please could someone provide some suggestions? I'm completely lost.
