 There are many online APIs that deliver paginated data. For instance, when we need a list of users, then we can fetch it page-by-page: a request returns a pre-defined count (e.g. 100 users), and provides an URL to the next page.

-3. We can get the next page URL from the `Link` header of the response. It has a special format, so we use a regexp for that. The next page URL may look like this: `https://api.github.com/repositories/93253246/commits?page=2`, it's generatd by Github itself.

 4. Then we yield all commits received, and when they finish -- the next `while(url)` iteration will trigger, making one more request.
