Looks interesting, thanks! Although after downloading all the available formats (PDF, ePub, and MOBI), each one shows that several chapters as unavailable, remarking that they are available "only in ebook."<p>Namely,<p>* Manage Cookies<p>* Work with HTTP Headers<p>* Redirects<p>* CORS<p>* Middleware<p>* Handling Forms<p>* File uploads in forms<p>* Setup Let's Encrypt for Express<p>Maybe I misunderstood, but is there another book that includes those chapters?
