Django just serves them from the filesystem, and doesn't cache them itself. You reload the page in your browser, and Django serves the files from disk Does the Django development server restart if you edit Templates? Because > it should also do that. Similarly, by default templates aren't cached, so on each view the dev server loads the templates from disk, parses them, and renders them.
