I'm nearly there too. In fact, I'm one closer than I was before this post.

i have a login thing...

index.asp has the login form on it, which passes information to check.asp which redirects to index2.asp if correct and index.asp if incorrect - that all works fine. I also have a logout page - however if you logout, you can still type the address to index2.asp and get there.

index.asp

Code: Select all

<html>
<head>
<title>Index</title>
<script>
function openit(){
var which="lost/lost.htm"
whichit=window.open(which,"","width=400,height=125")
}
</script>
</head>
<body>

      <form method="POST" action="check.asp">
	    <table border="0" width="122">
		  <tr>
		    <td width="121">
 		     <font face="Comic Sans MS" size="2">User ID</font>

 		     <input type="text" name="uid" size="15">
		    </td>
 		 </tr>
		  <tr>
		    <td width="121">
	        <font size="2" face="Comic Sans MS">Password</font>

 		     <input type="password" name="pwd" size="15">
		    </td>
		  </tr>
		  <tr>
		    <td width="121">
		      <input type="submit" value="Login Now!" name="B1">

              <font face="Comic Sans MS" size="2">
		      
              </font>
		    </td>
		  </tr>
		</table>
      </form>

</body>
</html>

check.asp

Code: Select all

<%
'here is the connection string
Set conn = server.createobject("adodb.connection")
'this connection uses JET 4 it is the prefered method of connecting to an access database
DSNtemp = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.Mappath("login.mdb")
'if you cant use JET then comment out the line above and uncomment the line below
'DSNtemp="DRIVER={Microsoft Access Driver (*.mdb)};DBQ=" & Server.Mappath("/slog/login.mdb")
conn.Open DSNtemp

'here we are getting the info from the login form
If InStr(Request.Form("uid"),"'") Then
uid = Replace(Request.Form("uid"),"'"," ")
Else
uid = Request.Form("uid")
End If
If InStr(Request.Form("pwd"),"'") Then
pwd = Replace(Request.Form("pwd"),"'"," ")
Else
pwd = Request.Form("pwd")
End If

'now we will querry the database for a match
SQL = "Select * From users Where uid = '" & uid & "' And pwd = '" & pwd & "'"
Set RS = Conn.Execute(SQL)

'if the user is found we will set the session okeydokey to TRUE allowing the user to gain entrance
If Not RS.EOF Then
  Session("okeydokey") = True
	
	'always always always destroy recordsets and close connections!
	Set RS = Nothing
	Conn.Close

'since the user was found, we sent them toodling on to the next page	
'########################################################################################################
'##### IN THE LINE BELOW CHANGE INDEX2.ASP TO THE PAGE YOU WANT THE USERS TO BE DIRECTED TO
  Response.Redirect "index2.asp"
Else
   
   'ooops if we got this far they dont know their login info or arent in the database
	'AGAIN always always always destroy recordsets and close connections!
	Set RS = Nothing
	Conn.Close
  'so we send em back to try again	
  Response.Redirect "index.asp"
'#####  CHANGE INDEX.ASP IN THE LINE ABOVE TO THE NAME OF THE PAGE WHERE
'#####  WHERE YOU PLACED THE LOGIN TABLE. LEAVE IT IN QUOTES!!!!!!!!!!!!
'##################################################################################
  
End If
%>

index2.asp

Code: Select all

<%Response.Buffer=TRUE%>
<%IF session("okeydokey") = FALSE THEN Response.Redirect "index.asp"%>
<html>
<head>
<title>YOUR IN!</title>
</head>
<body>
<font face="Comic Sans MS" size="2">Congratulations, your in!</font>


<font face="Comic Sans MS" size="2">Now some will say you can use
Session.Abandon to kill an active session. Never trust that. you can see that as
long as the browser is open you can hit the back and forward buttons all day
long. But try closing the browser and coming back to this page without first
logging in!</font>

Logout</p>
</body>
</html>

logout.asp

Code: Select all

<%

session("okeydokey") = FALSE
response.redirect("index.asp")

%>

can anyone help? please?!!!! :sad:

i've been looking at it, and i think it might be something to do with the page index2.asp being stored in the cashe, because if you refresh it, it does what it should do. Is there any code that i can put on the logout.asp code to delete the inde2.asp from the cashe?

benbacardi · #6 (**permalink**) Aug 11th, 2004, 19:45

ok i've discovered its only a problem in IE - anyone know a way round this? (sorry to keep replying to my own posts :sad

Hi Ben....

put the following before any html on each page you dont want cached:-

Code: Select all

<%
Response.AddHeader "Pragma", "no-cache"
Response.AddHeader "cache-control", "no-store"
%>

There are several other headers that will do the same thing, but this should work.
