Question

In my code i am maintaining some session on page load and some button click.
It works fine
but in browser if do Go back one page or go forward one page it disturb all session.

So what is the concept behind Go back one page, go forward one page in browser.

When we go forward or go back, does page reload from the server.

Answer 1

it depends by your configuration.

You can add the below code to your master page to force the reload for all the pages

protected override void OnInit(EventArgs e)
    {
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetNoStore();
        Response.Cache.SetExpires(DateTime.MinValue);

        base.OnInit(e);
    }
