Hi *, In an attempt to handle session timeouts, I'm wondering if someone on this list can enlighten me. My application utilises Zope's Transient Object Container & Session Data Manager. Once a user is authenticated, I set several variables in my Session Data Manager with the values from a HTML form - <dtml-call "REQUEST.SESSION.set('var1', var1 )"> <dtml-call "REQUEST.SESSION.set('var2', var2 )"> <dtml-call "REQUEST.SESSION.set('var3', var3 )"> Now these are variables are in my SDM, I set these in my standard_html_header as such... <dtml-call "REQUEST.set('var1',REQUEST.SESSION['var1'])"> <dtml-call "REQUEST.set('var2',REQUEST.SESSION['var2'])"> <dtml-call "REQUEST.set('var3',REQUEST.SESSION['var3'])"> This way I can access any session variables via <dtml-var var1> rather than <dtml-var "REQUEST.SESSION['var1']"> Am I on the right track so far? My problem is handling timeouts. My Trasient Object Container has a timeout value of 20 mins. In my attempt to handle timeouts, I have the following code in my standard_html_header - <dtml-if "REQUEST.SESSION.has_key('var1')"> the session still has this key, therefore must be active, do nothing. <dtml-else> <dtml-call "RESPONSE.redirect('login_page')"> </dtml-if> * The rest of my HTML code goes here. The problem is the redirect isn't working and Zope attempts to render the page... thus resulting in a Zope error. Does anyone have a working solution to this? or could point me in the direction of some Docs/HOW-TO's? Any help appreciated. Regards, Michael
