Refresh

A Refresh walk behaves like a Refresh All walk, but it doesn't check every URL every walk. The Webinator pays attention to how often each URL changes, and schedules checking the URL less often if a URL isn't changed. When a Refresh walk starts, it only refreshes URLs that are scheduled for update at the start of the walk.

The idea is that if a profile is doing nightly walks and a URL hasn't changed in the last 6 months, it probably doesn't need checked EVERY night. It can be checked every 2nd night, every 3rd night, every 5th night, etc. as it continues to not change.

  • When to use Refresh walks - Refresh walks are useful with a large (200k+ URL) collection of content that doesn't change very often, where the collection is too large to perform a Refresh All walk in a timely manner and dataload isn't possible. Refresh walks can finish much faster than a Refresh All walk. This allows another walk to start sooner and frequently-changing content to be re-checked sooner, instead of taking the time to finish refreshing all of the almost-never-changing content first.

    The downside of Refresh walks is that if a URL whose content rarely changes does change, it may not be picked up in the next walk because that URL may not be scheduled to be checked in the next walk. It may be worthwhile to schedule or manually launch an occasional Refresh All walk to check content slightly more often.
