Saving application state

Hello, it's me again :)

I have a POE-based application that queries a web app for some data
filtered on some time range, say, "send me any changes from time x to now".

The application will be running 24/7, and will query for more changes since
the last time it asked for changes. I have a tick handler that keeps the
heartbeat going every second so I can do the query repeatedly.

I need to save the last time it made the query in some persistent fashion
so I can pass it in my next query. I can't just save it to my heap in case
the application quits, I need to be able to resume the query since the last
successful query.

What is the best way of doing this, the "POE way". Can I just save it to a
file and read it back every tick count, which is 1 sec, using a regular
file handle?

Thanks in advance!

Celso
