Greetings,
I was wondering if there was a way of making a timer or a timed activity on a webpage. The purpose is a timed exam or test which the candidate will submit and be taken to another page based on the result. If the exam isn't submitted on time - it needs to end automatically. Being new to Ruby or RoR itself - I was hoping someone could point me in the right direction to solve this problem.
Thank you

This is done often on financial sites like banks and brokerages. Basically, you have to use two devices. The first is JavaScript on the client that does a redirect after time expires. Basically, you set a timer to the number of seconds the user has, then after that time expires, your JavaScript is called. That JavaScript just does the redirect:
window.top.location.href = 'http://someplace.else.com'
That solves half the problem. The other half is if the client has JavaScript turned off. For that, you need to store a last-access time in the session. So, before serving a page, simple do this in your controller:
session[:last_access] = Time.now
Then before serving the next page:
redirect_to(:action => 'time_out' and return if session[:last_access] < 5.minutes.ago
I don't know if this applies to all actions in your controller or only some of them. If all of them, consider writing a before_filter.
