How Disable Browser Back Button only after Logout in mvc3.net
Use this code in the html page on which you need to control the back button.
$().ready(function() {
if(document.referrer != 'http://localhost:8181/'){
history.pushState(null, null, 'login');
window.addEventListener('popstate', function () {
history.pushState(null, null, 'login');
});
}
});
This code will block back button event. The if condition is for allowing the back button if the previous page is 'http://localhost:8181/'. Back button won't be working if the previous page is not 'http://localhost:8181/'. If you need to block all previous pages then avoid the if condition. The history.pushState statements will replace the url on the browser address bar to 'login'. So I recommend you to change 'login' with your page url.
Advantages of this method:-
- No need to control the cache.
- We could allow the back button event for specified previous pages and could block the rest.
Hoping my answer will help someone.
You could clear the browser history when the user logs out:
var url = window.location.href;
window.history.go(-window.history.length);
window.location.href = url;
However this would not be particularly robust - it relies on javascript, it would not work across multiple tabs and may only serve to annoy the user. IMO the best bet is to set appropriate caching headers such that the browser will not cache any of your 'logged in' pages via a NoCacheAttribute applied appropriately:
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.SetRevalidation(HttpCacheRevalidation.AllCaches);
filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
filterContext.HttpContext.Response.Cache.SetNoStore();
base.OnResultExecuting(filterContext);
}
}
The easiest way I found is using OutputCache Attribute
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
public class HomeController : Controller
{
}
Disabling back button is not a right way to achieve your need. Instead you can add the following three tags in your html file, which takes care of clearing cache.
<META Http-Equiv="Cache-Control" Content="no-cache">
<META Http-Equiv="Pragma" Content="no-cache">
<META Http-Equiv="Expires" Content="0">
