I'm doing some work on a data acquisition system for
temperature sensors. The displayed readings don't change
much over time, so what I would like to do is to force a
page refresh only when the data changes by 5% or more, or
when the temperature is over a limit.

So far my options seem to be frequent page refreshes using a
meta tag, or using Java. The meta tags are a fixed time
interval and may be too frequent (or not frequent enough),
and the Java may be a problem because some companies have
some strict Java rules to security. Any other ideas?

Thanks,
Dave
