If a user comes to a page that needs a login, I give them an error
and a link to a login page. I have the login set a cookie and then
returns the user to the original page that needed a login:
<cfcookie name="fsnep_login" value="#validate_user.login_id[1]#">
<cfset the_loc = "#session.return_url##del#login_return=true">
<cflocation url="#the_loc#" addtoken="no">
It returns to the url with a url variable. With the return variable
attached, the page then checks for the cookie and allows the user
in. And if the user chooses to use the logout button, it works fine
(foreshadowing).
Unfortunately without the url variable attached, it doesn't correctly
find the cookie and says that the user must log in again. So if
they're returned to the page with the url variable attached, they are
"logged in", otherwise, it appears that they're not, even though they
are. I do the check like this:
<cfif NOT isDefined('cookie.fsnep_login')>
Now, if I change it to <cfif NOT structKeyExists(cookie,'fsnep_login')
>, it works fine. I can go to the page, it asks for a login, I
login and am returned, works fine. I then type in the page, without
the url variable appended and it still works fine. The cookie is
there and it sees it. Unfortunately with this scenario, when the
logout button is clicked, and then I return to the page, it still
acts as if I'm logged in, unless I append a url variable <sigh>. ???
Here's the logout code:
<cfset j = structDelete(cookie,'fsnep_login',true)>
<cfcookie name="fsnep_login" expires="now">
<cfset k = structDelete(session,'return_url',true)>
<cfset i = structDelete(session,'fsnep_login',true)>
This is on PC IE
thanks for any help.
