[Repost]How to Expire Session in asp.net when we click on browser back button

Question

1.00/5 (1 vote)

See more:

I have one normal Login page ,1 Master Page as "ABC.Master" and 3

child pages as page 1, page 2, page 3. The page 1,page 2, page 3 are the child

pages of Master Page "ABC.Master".

After entering the Username and Password if I click on Login it moves to the Page

1 and from Page 1 if I click on some links it moves to Page 2. And from Page 2

if I click on the Browser Back button it should go back to Page 1 and then if I

click on Page 2 or Page 3 link then the Session should get expired.

Note: It should be purely like Banking website. i.e) On clicking the Browser back

button the Session has to get expired.

Solution 1

use this for session clear

protected void Page_Init(object sender, EventArgs e)
       {
           Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));

           Response.Cache.SetCacheability(HttpCacheability.NoCache);

           Response.Cache.SetNoStore();
       }

Use this in page after

Session.Abandon();

Hi Salman Thanks for ur reply.. In the place of ["YourKey"] what to give ? As there is a no keycode for the browser back button. There is keycode for the keyboard keys not for the browser buttons

Replace "YourKey" with the Session Key You want to Clear.

Salman..!! As i'm using Master page here . if i write this code in Master page load then it wont work because all the child pages are under master page. if i move forward from page 1 to page 2 also it has to go Masterpage and if i move back from page2 to page1 also it goes to back to Master page. How it will will know whether i'm clicking on other pages link or i clicked on the browser back button??
