c# - How to actually logout from a website rather than simply redirecting to login page? -

-

i using response.redirect facility send user login page when clicks logout image button not perform logout operation , when user clicks backspace button in keyboard or button in browser user screen gets displayed back. how control situation in c# asp.net , have read posts saying session should cleared before redirecting dont know how apply in form. have enclosed coding below , request me out of situation in clear manner.

in loginpage.aspx

protected void btnlogin_click1(object sender, eventargs e) { var query = (from row in db.logins row.userid == txtuname.text && row.password == txtpassword.text select new { row.userid, row.password, row.admin_roll, row.manager_roll}).distinct(); if (query.count() > 0) { if (query.single().admin_roll == 1) { response.redirect("~/homepage.aspx"); } else if (query.single().manager_roll == 1) { response.redirect("~/detailspage.aspx"); }

and in masperpage.master

protected void imagebutton1_click(object sender, imageclickeventargs e) { response.redirect("~/loginpage.aspx"); }

suggest me solution.

for have clear session , cookies browser using c# code.

  • logoutpage.aspx

`

protected void page_load(object sender, eventargs e)         {             response.cache.setcacheability(httpcacheability.nocache);             response.cache.setexpires(datetime.utcnow.addhours(-1));             response.cache.setnostore();             session.abandon();             session.clear();             system.web.security.formsauthentication.signout();                 // not redirect login page here             // redirect login page javascript          }

`

and same way have clear browser history using javascript on page load

`

<script type="text/javascript">     $(document).ready(function () {                     var url = window.location.href;         window.history.go(-window.history.length);         window.location.href = 'login.aspx'; // redirect login page     });  </script>

`

updated answer: better make different page logout logout.aspx , write code in page_load event of logout.aspx page. , write above javascript in <head> tag in logout.aspx page.
