Hello everyone,

I have a small problem...
The general idea is:

1. Get the maximum time of inactivity(t1) of a web page when a HTTP session expires.
2. While another window is open, check the time of inactivity (t2) of this page.
3. When t1=t2 make a refresh to the page.

Does anyone has a suggestion on how can i do this?

Thank you for your help.
