Hi all,

I have set a session session to expire after an hour by doing:  
session[:expire] = { :expires =\> 1.hour.from\_now }  
What I would like to do is have it so that session gets reset back an  
hour whenever a new page is loaded. If, however, the session variable  
has expired and the user tries to load a page I want my app to kick them  
back to a loggin page. I have tried to achieve this by saying:

if !(session[:expire].blank? \< 0.hour.from\_now)  
session[:expire] = { :expires =\> 0.25.hour.from\_now }  
end

However, it doesn’t like the session[:expire]. It gives me:

You have a nil object when you didn’t expect it!  
You might have expected an instance of Array.  
The error occurred while evaluating nil.[]

even though I am saying if session is blank. Is there another way to do  
this. Thanks,

-S

Have a look at the sliding\_session\_timeout plugin:
