Question

How can I clear browser cache only on logout, sure I can use the below:

Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
Response.Cache.SetNoStore();

But this particular page which is a shopping bag page is accessible by both login and non-login users. How can I set it in such a way whereby the login user is able to access this page without clearing the browser cache but Only clears it when he/she logs out so that another user will not be able to access the history contents.

I have tried the solutions here:
http://www.codeproject.com/Tips/135121/Browser-back-button-issue-after-logout
made some changes but still couldn’t figure out how to deal with this issue.

I also cleared my session on logout as below but I understand the browser cache will still stay.

FormsAuthentication.SignOut();
Session.Abandon();
Response.Redirect("~/");

Please advice. Thanks.

I am not a c# expert, but I am pretty sure what you have above only tells the browser to not cache the page you are on. There is no way to tell the browser to clear cache on any page. This would be a problem if there was such a way. Sounds like the solution you need is to not cache any page at all, regardless of logging out or not.
