ASP.NET MVC – Prevent Browser Back Button Openning Page After Logout

If you have ASP.NET MVC application with login / logout functionality (for example using Forms Authentication), you may have noticed that after logout, if you hit back button in your browser, last page you were on will open. In secure application this could present a problem, as it could expose information that only authorized users should view.

Culprit in this scenario is our browser, as it will quite happily show cached version of the page after you’ve logged out.

There isn’t much you can do, except tell your browser to not cache your application’s pages. You can do this for individual pages in your applications, or if you want all pages not to be cached, you can add an event in Global.asax file.

Add Application_BeginRequest() method to your application’s Global.asax file, and add code below which will disable browser caching for each request.

        protected void Application_BeginRequest()
        {
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
            Response.Cache.SetNoStore();
        }

How to Force Refresh iOS App Store

If you wish to refresh iOS App Store, you can either force close and re-open it, or you could force refresh content right from the App Store itself.

To force refresh App Store, tap 10 times on one of the options at the bottom – Featured, Top Charts, Explore, Search or Updates. Make sure you pick one option and tap on it 10 times (e.g. tap 10 times on Updates), rather than tap on different options.

Once you’ve tapped 10 times, App Store content will reload, along with any updates as well.

Font Awesome and IIS

If you are using Font Awesome in your ASP.Net web app which is hosted on IIS, you need to set appropriate mime type for Font Awesome files, otherwise IIS won’t know how to serve them.

To do this, you’ll need to add mime type mapping to <system.webServer> section in your application’s Web.config file.

Before registering each file extension (woff and woff2), we’ll want to remove them first, just in case that mime types for those are already registered on IIS host.

<system.webServer>
<staticContent>
<remove fileExtension=”.woff” />
<mimeMap fileExtension=”.woff” mimeType=”application/x-font-woff” />
<remove fileExtension=”.woff2″ />
<mimeMap fileExtension=”.woff2″ mimeType=”application/x-font-woff2″ />
</staticContent>
</system.webServer>
