动态站点，全局访问会话

您好，我目前正在为我的学校开发一种维基系统，该系统使用子域来查找维基属于哪个课程。例如 math1.wiki.com 将是数学 1 课程。现在，所有这些 wiki 使用相同的数据库，并被赋予一个 wiki id，以查找要加载的数据。

这是我用来查找 wiki id 的代码。 Global.asax

    protected void Session_Start()
    {
        var database = new DataContext();
        IWikiRepository rep = new WikiRepository(database);
        IWikiService service = new WikiService(rep);

        var domain = HttpContext.Current.Request.Url.Authority;
        var port = "";
        if (domain.Contains(':'))
        {
            var tmp = domain.Split(':');
            domain = tmp[0];
            port = tmp[1];
        }
        var split = domain.Split('.');
        var subdomain = split[0];

     //   if (subdomain == "localhost")
     //       subdomain = "wiki1";

        var wiki = service.GetSite(subdomain);

        if (wiki == null)
        {
            Response.StatusCode = 404;
            return;
        }

        Session["CurrentWiki"] = wiki;
    }

这一切都很好，但如果没有找到子域的 wiki，我想让 mvc 系统发送 404 请求。但这不仅可以在 session_start() 中完成，因为它每个会话只运行一次，因此我尝试使用 Application_BeginRequest，但遗憾的是我无法访问该方法中的会话。

有谁知道我该如何实现这一点？

Hello i am currently developing a kind of wiki system for my school, this system uses sub domains to find what course the wiki belongs to. example math1.wiki.com will be the course Math 1.
Now all these wikis use the same database and are given a wiki id, to find what data to load.

Here is the code i use to find the wiki id.
Global.asax

    protected void Session_Start()
    {
        var database = new DataContext();
        IWikiRepository rep = new WikiRepository(database);
        IWikiService service = new WikiService(rep);

        var domain = HttpContext.Current.Request.Url.Authority;
        var port = "";
        if (domain.Contains(':'))
        {
            var tmp = domain.Split(':');
            domain = tmp[0];
            port = tmp[1];
        }
        var split = domain.Split('.');
        var subdomain = split[0];

     //   if (subdomain == "localhost")
     //       subdomain = "wiki1";

        var wiki = service.GetSite(subdomain);

        if (wiki == null)
        {
            Response.StatusCode = 404;
            return;
        }

        Session["CurrentWiki"] = wiki;
    }

This is all fine, but i want to make the mvc system send a 404 request if no wiki was found for the subdomain. But this can not only be done in session_start() as it only runs once per session i have therefor tryed using Application_BeginRequest, but sadly do i not have access to the sessions in the method.

Do any one know how i can implement this?
