在asp.net中設置當前用戶mvc

我不確定這是否是實現它的最佳方式，但我希望在當前用戶的所有請求期間保持用戶對象處於活動狀態。從閱讀幾個資源，我瞭解到，你應該創建自己的原則，它擁有這一點。但我不想每個認證請求觸發數據庫。有關如何處理此問題的任何建議？緩存數據庫請求是個好主意嗎？在asp.net中設置當前用戶mvc

protected void Application_AuthenticateRequest(Object sender, EventArgs e) 
    { 
     HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName]; 
     if (authCookie != null) 
     { 
      FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value); 

      User user; 
      using (HgDataContext hg = new HgDataContext()) 
      { 
       if (Session["user"] != null) 
       { 
        user = (from u in hg.Users where u.EmailAddress == authTicket.Name select u).Single(); 
       } else 
       { 
        user = Session["user"] as User; 
       } 
      } 
      var principal = new HgPrincipal(user); 
      Context.User = principal; 
     } 
    }

這個問題似乎還不清楚。你想要保持什麼樣的對象？在任何情況下，你的代碼片段都不能保持任何對象的活着，所以這裏似乎有錯誤。但是，如果不知道你想要達到什麼目的，我什麼都不能說。你能否詳細說明一下？ – 2010-04-19 12:07:46

我儘量保持我的用戶對象 – TomHastjarjanto 2010-04-21 19:30:17

我現在正在使用以下緩存用戶的代碼，注意在更新後刪除緩存！

protected void Application_AuthenticateRequest(Object sender, EventArgs e) 
     { 
      HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName]; 
      if (authCookie != null) 
      { 
       FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value); 

       User user; 
       Cache cache = HttpContext.Current.Cache; 
       using (HgDataContext hg = new HgDataContext()) 
       { 
        user = cache[authTicket.Name] as User; 
        if (user == null) 
        { 
         user = (from u in hg.Users where u.EmailAddress == authTicket.Name select u).Single(); 
         cache[authTicket.Name] = user; 
        } 
       } 
       var principal = new HgPrincipal(user); 
       Context.User = principal; 
      } 
     }
