Hello, I am testing out how to protect pages in coldfusion and have run into an issue when attempting to create a process by which users can log out.
Essentially, I have three pages:
- Page A - The form that submits to Page B
- Page B - That checks the form.username and form.password against a database (works fine)
- Page C - Logout page (Which is where I am having an issue).
Page C throws a "variable Session is undefined" error
Here is the code on Page C:
<cfset StructClear(Session)>
<cflocation url="index.cfm">
Here is the code on Page B:
<cfif NOT IsDefined ("form.username")>
<cflocation url="index.cfm" addtoken="No">
</cfif>
<cfquery name="test" datasource="cfdb">
SELECT * FROM USERS
WHERE USERNAME = '#FORM.username#'
AND PASSWORD = '#FORM.password#'
</cfquery>
<!---<CFSET Session.LoggedIn = "1">
<CFSET Session.FirstName = "#test.FirstName#">--->
<CFIF test.RecordCount IS 0>
<cflocation url="index.cfm" addtoken="No">
<CFSET StructClear(Session)>
<cfelse>
<CFSET Session.LoggedIn = "1">
<!---<cflocation url="test.cfm" addtoken="No">--->
</cfif>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
<p><a href="logout.cfm">Log Out</a></p>
<p> </p>
<p> </p>
<p><br>

</html>
As you can see, nothing fancy 
Now, I thought that the Session variable could be accessed by any page within a given browser instance, but I am obviously wrong.
What do I need to do for Page C (my logout page to be able to access the session variable).
Any guidance is greatly appreciated!
