You still don't get it.

No you don't. You said:

"While you can set a session timeout value on the server, you can't
force the client to a different page from the server.  It requires a
request from the client."

You don't understand because you assume that any request will *always*
reset the session timeout and you assume that relying on PHPs own
session handling is the only way to go.
