Hi
I currently use an automatic logout out system that sets a time out in
two ways.
(If the ip address on computer is recognized then set timeout to 10
mins, if not then set to 2 mins.)
1) The time out setting is used to create a meta refresh tag that will
re-direct the user to the logout page after X seconds.
2) At the beginning of each page i set a variable with the current time
and check to see if the difference between the previously set variable
and the now current time is greater than X seconds, if so then log the
user out.
I know meta refresh is not to be relied on and that is why i use the 2nd
method as well, but i have had varied reports that this system does not
work, i.e. it logs people out to quickly.
Does anyone know a better way of doing this or improvements?? it would
also be nice to stop the pages displaying after a time out when a user
presses the back button!
Thanks a lot in advance
Adrian
