BeginRequest-like filter in MVC 3?

阅读更多关于 BeginRequest-like filter in MVC 3?

问题 I have some code in my application that I need to execute on every request, before anything else executes (even before authentication). So far I've been using the Application_BeginRequest event in my Global.asax, and this has worked fine. But this code needs to hit the database, and doing this from Global.asax doesn't feel right for some reason. Also, the Ninject.MVC3 nuget I'm using won't inject dependencies into my HttpApplication ctor. So what I decided to do is move this code into its own

what alternatives are there to using global.asax?

阅读更多关于 what alternatives are there to using global.asax?

I am using my own custom authentication with IIS, and I want the server on every page load (no matter what type of file) to first check the Application variable to see if the user is authenticated and authorized to see the site. In global.asax this could be: void Application_Start(Object Sender, EventArgs e) { if(Application["username"] == null) { Response.redirect("login.aspx"); } } The problem is that this site has multiple sub-roots.
