Minimum Refresh Time

Syntax: choose from drop down list

For Refresh-type walks, this is the minimum time period to try refreshing a URL. The actual refresh period is dynamically computed for each URL based on how often it changes, and will not be less than this value. This prevents too much time being spent refreshing a very dynamic page (i.e. constantly refreshing it and loading the web server). Typically set to 1 minute.
