I had this problem a while ago, disabling the cache for the entire application solved my problem, just add these line to the Global.asax.csfile
不久前我遇到了这个问题，禁用整个应用程序的缓存解决了我的问题，只需将这些行添加到Global.asax.cs文件中
protected void Application_BeginRequest()
{
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
Response.Cache.SetNoStore();
}
Hope this helps.
希望这可以帮助。

You need to add the cache METATag for all the last page you visited
您需要为META您访问的所有最后一页添加缓存标签
So add this for all the pages, by making a CustomAttribute like [NoCache]and decorate
所以为所有页面添加这个，通过创建一个像[NoCache]和装饰的 CustomAttribute
public 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.SetCacheability(HttpCacheability.NoCache);
filterContext.HttpContext.Response.Cache.SetNoStore();
base.OnResultExecuting(filterContext);
}
}
public class AccountController : Controller
{
[NoCache]
public ActionResult Logout()
{
return View();
}
}
Or try it with javascript on the page like
或者在页面上尝试使用javascript
<SCRIPT type="text/javascript">
window.history.forward();
function noBack() { window.history.forward(); }
</SCRIPT>
<BODY onload="noBack();"
onpageshow="if (event.persisted) noBack();" onunload="">

Easiest way for a MVC 5 Application is:
MVC 5 应用程序的最简单方法是：
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "None")]
Above each of the Controller Methods you don't want to Cache. Or if you are using .Core the following works:
在您不想缓存的每个控制器方法上方。或者，如果您使用的是 .Core，则以下工作：
[ResponseCache(Location = ResponseCacheLocation.None, NoStore = true)]
Have a nice day!
祝你今天过得愉快！

you can use onClick event of javascript to prevent browser back. for example:
您可以使用 javascript 的 onClick 事件来防止浏览器返回。例如：
<a onclick="noBack()" href="#">Logout</a>
<Script type="text/javascript">
window.history.forward();
function noBack() { window.history.forward(); }
</Script>
Hope this will help you, Happy Coding!
希望这会帮助你，快乐编码！

protected void Application_BeginRequest()
{
Response.Buffer = true;
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1d);
Response.Expires = -1500;
Response.CacheControl = "no-cache";
Response.Cache.SetNoStore();
}
Add [Authorize] filter on each controller
