# Looping docs moved in Duaer

In Duaer, legacy URL. Per-item execution and Execute Once are on the flow-logic looping page.
## Open the current page

Paths that end in .html are leftovers from older docs. Read [run per item or once](/flow-logic/looping.md) instead. When the canvas says a node ran multiple times, that notice should open that page too.
## Questions

### Why does Duaer still have a looping URL that ends in .html?

It is a legacy link. How Duaer runs per item or once is at /flow-logic/looping/. Use that page when you open the old address.
