Hello everyone,
I created a logon page using C# ASPX, I have the user logon and if logon
information is correct I do a Response.Redire ct(url); On the second page it
displays data and I have a logoff button which does another
Response.Redire ct(main url); Here is the issue, I am able to browse back to
that page and the data is still populated and visible. How can I clear the
cache for that page? I have tried:
Response.Expire s = 0;
Response.Expire sAbsolute = DateTime.Now;
Page.Response.C ache.SetCacheab ility(HttpCache ability.NoCache );
And no such luck. I would appreciate the help.
Thank you,
Terry

Try using session variables.
set a session variable saying the user is "authentica ted" when the user
logons.
and on logoff, set that variable to say the user is not authenticated.
and on the second page, right at the top, check that session variable to see
if the user is authenticated or not.....if not...redirect the user back to
logon page.

I have had a similar problem with a shopping cart checkout page. Once the
user checks out you don't want them going back to this page.
What I did was add this to the checkout page
<head>
<script language="javas cript">
history.forward ();
</script>
</head>
This gives the effect of a disabled the back button. So what happens is when
the user leaves the checkout page and then tries to use the back button, they
are redirected back to the page they are currently viewing... hence they can
never use the back button to go back to the checkout page.
You may be able to use a trick like this. Just add that code to the logon
page and the user will never be able to go back to that page using the back
button.
Hope this helps.

Hi All
We have an ASP application which tracks holidays for our employees. When the
user logs in we store thier username in a session variable and use that
variable when displaying and adding data to the access database. The
username is the primary key for the database table.
strUsername = request.form("UserName")
set RS = server.createobject("ADODB.recordset")
MySql="select * from empprofile where empname ='" & strUserName & "'"
