Probably by asking somewhat less question here.

You could have Google to search first. If you find it hard or getting stucked to any point then you can come here.

Try for more then 10 min, you can not get solution easily.

If you'll be habitual to get help from others always, You will never learn anything from yourside, Just show some tendency to learn and you'll have you answer.

That is not a Correct Term. Tell me if i misunderstood your question.

When the User logout on your app,if they try to access your app again , you want to send them to a login again before they enter ?

Vuyiswa Maseko,

Spoted in Daniweb-- Sorry to rant. I hate websites. They are just wierd. They don't behave like normal code.

Ok , What you need to do, is that When He Successfully logged in , you need to store his username on the Session e.g

if(Success)
{
Session["Username"] = "The Username";
}

this code should in your Login Button , and when the User Decides to Logout , then You need to clear the Session , e.g

Session["Username"] = null;

Now on the Page load event of every page , you need to Check if the User has logged in , if the Session is Null, it means that the user has not logged in, then you can Redirect that user to the Login page. e.g

 if(Session["Username"] == null)
{
   Response.Redirect("Login.aspx",false);
}

make sure that this code is not inside a code like this

if(!page.ispostback)
{
}

Keep it outside , so that it will always check it.

Hope this helps

Your question is not worded properly. But, as per your question, what I understood it, If user sign out from your application, you don't to revisit the page again and insted of that you want to show "Page Can't be displayed"

Use Session.Abandon() when user sign out from your application.

and check the Session Variable for null on the page_load in your page, if it's null, redirect to "can't displayed page"

as,

If(Session["UserName"] == null)
{
  Response.Redirect("PageNotDisplayed.aspx"); 
}
else
{
  // Do your staff.
}

Cheers !

Well, browers back button does not reloads the whole page and so I have to disagree with other replies about clearing the session. It happens, because of browser cache and you need to clear that out after logout.

Try:
code for clearing cache can be put up in code behind as follows:

// Code disables caching by browser. Hence the back browser button
// grayed out and could not causes the Page_Load event to fire 
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
Response.Cache.SetNoStore();

You can add somethin similar in form aspx if you want to place it there:

<META Http-Equiv="Cache-Control" Content="no-cache">
<META Http-Equiv="Pragma" Content="no-cache">
<META Http-Equiv="Expires" Content="0">

OR

You can clear browser history through JavaScript....

JavaScript

//clears browser history and redirects url
<SCRIPT LANGUAGE=javascript> {  var Backlen=history.length;   history.go(-Backlen);   window.location.href=page url }</SCRIPT>

Page.ClientScript.RegisterStartupScript(this.GetType(),"cle","windows.history.clear",true);

OR as you say in you logout event:

protected void LogOut()   
{       
     Session.Abandon();       
     string nextpage = "Logoutt.aspx";       
     Response.Write("<script language=javascript>");             
     Response.Write("{");       
     Response.Write(" var Backlen=history.length;");       
     Response.Write(" history.go(-Backlen);");       
     Response.Write(" window.location.href='" + nextpage + "'; ");
     Response.Write("}");       
     Response.Write("</script>");   
}

Had you searched this very site 'Question & Answer' section, you would had found this answer.

He didn't mentioned it any where that, he want to navigate it using browser back button. So, I don't think other answer are wrong. Yes, On back button it's never reload the page, but what about copy the previous url and paste it in different tab ?

BTW: your answer is well explained +5, I will suggest you to put it as Tips n Ticks in CP and in future you / we can use the same from there Smile | :)

Here[^]... he explained it while discussing the previous answer. I won't blame you or other answerers for the session thing as OP failed to explain his problem properly in the first place itself.

You are asking an awful lot of questions (here and in Database) which with a little bit of research you could answer yourself. The quesiton above is basic HTML stuff.

Enough now. Do some work yourself.

Better to use POST in the form's ACTION property to just pass values from one page to another.
