form/user data timing out ?

[Oliver]

Hi all,
    ...I've implemented a simple form based search page which presents
results 10 at a time on request.

    It works fine...nearly. If the user does a search, but then doesn't
touch their browser for a couple of minutes then the embperl page seems
to lose their data.

    so is there a time-out going on here, or is a server process dying
naturally ?
    I've looked at the docs for Apache::Session (used by Embperl I'm
thinking), but no luck yet.

    suggestions appreciated,
    Oliver.
