<CFLOGIN>

I am using <CFLOGIN> to authenticate users. When users log in using the <CFLOGIN>, how is there status (logged in/out) stored??? I want to create a <CFLOGOUT> tag only if the user is logged in. I need to know what to look for or what variable to test for to see if the user is logged in.

<cflogin> framework has a function called GetAuthUser().
once the user is logged in, you can use this function to retrieve or display the user's name, id or any other identifying information.

i am sure you are also using something like
<cfloginuser
name = "#yourquery.ContactID#,#yourquery.FirstName#"
password = "#FORM.userPassword#"
roles = "#yourquery.userRoleName#">

then you will do

<cfset contactID = ListFirst(GetAuthUser())>
<cfset contactName = ListRest(GetAuthUser())>

assuming the fact that user successfully logged in, you can check for the existence of contactID and contactName.
<cfif IsDefined('contactID')>
...user is logged in, provide the logout button...
</cfif>

hope it helps...
