Site and Origin

The concepts of Origin and Site may be confusing, yet they are important because browsers make security decisions based on the fact whether two interacting contexts are in the same origin or in the same site.

In this webpage, you can enter two URL addresses and compare their Origins and Sites. The list of sites is always up-to-date because this page downloads the Public Suffix List directly in your browser.
