MVC 6-注销后防止缓存 [英] MVC 6 - Prevent Cache After Logout

问题描述

我正在使用MVC 6，并且已经实现了Identity 3.0进行身份验证.

I'm using MVC 6 and I have implemented Identity 3.0 for authentication.

我正试图阻止用户注销后单击浏览器的后退按钮.我遇到的最接近的可行解决方案似乎在MVC 6中无法正常工作.

I'm trying to prevent the user from clicking on the browser back button after logout. The closest working solution I came across seems to be not working in MVC 6.

有人可以帮忙吗?

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public sealed class NoCacheAttribute : ActionFilterAttribute
{
public override void OnResultExecuting(ResultExecutingContext filterContext)
{
    filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
    filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
    filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
    filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
    filterContext.HttpContext.Response.Cache.SetNoStore();

    base.OnResultExecuting(filterContext);
}
}

推荐答案

您可以使用它.

    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
    public sealed class NoCacheAttribute : ActionFilterAttribute
    {
        public override void OnResultExecuting(ResultExecutingContext filterContext)
        {
            filterContext.HttpContext.Response.Headers.Add("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
            filterContext.HttpContext.Response.Headers.Add("Pragma", "no-cache"); // HTTP 1.0.
            filterContext.HttpContext.Response.Headers.Add("Expires", "-1"); // Proxies.

            base.OnResultExecuting(filterContext);
        }
    }
