I am using the following for to peroidically call back to the control to  
see if a certain amount of time has passed:

in .rhtml  
\<%= periodically\_call\_remote :url =\> {  
:action =\> ‘session\_expiry’ },  
:update =\> ‘’ %\>

in controller  
if !session[:expire].blank?  
@time\_left = (session[:expire][:expires] - Time.now).to\_i  
else  
@time\_left = 0  
end

if @time\_left.to\_i \< 0 or @time\_left == 0  
flash[:notice] = “**You have been logged out  
due  
to inactivity**”  
session[:user] = nil  
redirect\_to :action =\> ‘login’  
end

The idea being that if too much time has passed the user gets signed out  
and get kicked back to the login page. Everything work right, except the  
bit of code that check to see if an hour has passed since the users last  
action and then it is supposed to redirect\_to a login form. The problem  
is that when it gets to that redirect\_to it seems to skip right over it  
and not do anything, even worse, it allows the user to continue to be  
logged in. Has anyone used peroidically\_call\_remote before and has  
similar issues and how did you fix them? Thanks,

This has nothing to do with periodically\_call\_remote and everything to  
do with it being an ajax request.  
If you want to redirect from an ajax request you need to use rjs (ie  
remove the update option from periodically\_call\_remote) and use  
page.redirect\_to from the rjs
