This is a followup to a recent post to this group. The snippet below imports a page and stores it into variable x if variable x is more than 5 five minutes old. This makes the page load fast for the great majority of hits.
However, if traffic to the site is slow, let's say a steady one hit every 6 minutes, then each surfer experiences a very slow response time as the site goes through the slow c:import routine to load x before showing the page. Meanwhile, my webserver is sitting idle for the remaining time between hits. Is there a tag or other technique one can use to instruct the webserver to keeps variable x up-to-date (ie, not more than 5 minutes old) in the background without waiting for a hit before noticing the variable is stale?
