Hi,

I am using sessions in my application and file store for sessions
storage.

now i want to expire my session after some short of idle time.for that
i need the start time of the session.

Does Any one know how can i get start time of the session ??

Thanks in Advance.

Restful authentication / acts_as_authenticated does this by using a
database field and setting a cookie. Perhaps you could take a look at
the source code of that.

Thanks for your response Ryan… I found one another and easy way for
doing same without getting start time for sessions.

For doing session timeout after some idle time we can go with below
thing.

  1. Define below filter and methods in application.rb file.

before_filter :update_activity_time, :except => :session_expiry

          def update_activity_time
               session[:expires_at] = 10.minutes.from_now
          end

           def session_expiry
               @time_left = (session[:expires_at] - Time.now).to_i
                unless @time_left > 0
                reset_session
                render update do |page|
                      page.redirect_to path for login page
                end
           end
  1. Add below remote periodic call to the layout.

<%= periodically_call_remote :url => {
:action => ’ session_expiry’ },
:update => ’ ’ %>

Thats Done !!

In case it matters, periodically_call_remote requires javascript… so
if
a user disables JS, your example doesn’t work unless you do that expiry
check before every request as well.
