What is the name for the strategy of naming static web content with a hash of the content to enable long caching times?

Question

E.g. naming your JavaScript as foo-e65325060020bef3804f867dd6bae598.js, where e65325060020bef3804f867dd6bae598 is a hash of the content of the file.

This is fingerprinting:

It allows you to send a link to a different file-name when a peripheral asset file (javascript, css or image files) changes on the main webpage. The change in file-name causes the browser to re-download any assets which have been changed.
