The Refresh processor allows the user to toggle the page between automatically reloading after a certain amount of time, or just sitting there statically.

{{{#!Refresh
interval=5
default_status=disabled
}} }

This will show a link on the page like so: Enable auto-refresh of this page

Clicking on the link will start the page auto-refreshing at 5-second intervals. When enabled, the link shown will be: Disable auto-refresh of this page

The processor works by editing the block.
