Ask HN: How does Google Analytics, a client-side script, get referring URLs?

Shower thought: given that Google Analytics is installed by dropping a JavaScript snippet onto the page, how does Google get the referring page when visitors land on the page via link or search result, etc.?

The script should be able to read `Document.referrer` and post the result to wherever it wants.
