在ASP.Net自定义缓存校长 [英] Custom Principal Caching in ASP.Net

问题描述

我成功地与ASP.NET自定义主要的工作，但我的自定义主体的负载数据库中的数据，我不希望这种事情发生在每次请求到系统中。

我打开我的自定义主体在Application_OnPostAuthenticateRequest的Global.ascx文件，但它似乎会话状态不可用在这里。我在哪里假设第一个请求进入系统后，坚持下去，这样我就不必继续从头开始重新呢？

 保护无效Application_OnPostAuthenticateRequest（对象发件人，EventArgs的发送）
        {
            主要的IPrincipal = HttpContext.Current.User;            如果（principal.Identity.IsAuthenticated ==真＆放大器;＆安培; principal.Identity.AuthenticationType ==联合会）
            {
                CustomPrincipal customPrincipal = NULL;
                    IClaimsPrincipal claimsPrincipal =（ICla​​imsPrincipal）负责人;                    如果（claimsPrincipal == NULL）
                    {
                        抛出新ApplicationException的（我们应该有在这一点上声明主体）;
                    }                    customPrincipal =新CustomPrincipal（claimsPrincipal）;
                HttpContext.Current.User = customPrincipal;
                = Thread.CurrentPrincipal中customPrincipal;            }
        }
 

解决方案

使用缓存，而不是会议

I am successfully working with a custom principal in ASP.NET, but my custom principal loads database data and I don't want that happening on every request into the system.

I load my custom principal in the Global.ascx file in the Application_OnPostAuthenticateRequest, but it appears session state is not available here. Where am I suppose to stick it after the first request into the system so that I don't have to keep recreating it from scratch?

 protected void Application_OnPostAuthenticateRequest(Object sender, EventArgs e)
        {
            IPrincipal principal = HttpContext.Current.User;

            if(principal.Identity.IsAuthenticated == true && principal.Identity.AuthenticationType == "Federation")
            {
                CustomPrincipal customPrincipal = null;


                    IClaimsPrincipal claimsPrincipal = (IClaimsPrincipal)principal;

                    if (claimsPrincipal == null)
                    {
                        throw new ApplicationException("We should have a claims principal at this point");
                    }

                    customPrincipal = new CustomPrincipal(claimsPrincipal);


                HttpContext.Current.User = customPrincipal;
                Thread.CurrentPrincipal = customPrincipal;

            }
        }

解决方案

Use the Cache instead of session
