• Domains using oauth.do have a */login* route bound to the oauth-do worker.
• https://database.do/login hits the /login route in oauth-do, and is redirected to the shared login service at https://oauth.do/login if not previously logged in.
• If the user has not logged into oauth.do, they are redirected to the oauth provider:
• https://github.com/login/oauth/authorize?
• Once authorized, GitHub redirects the user back to:
• https://oauth.do/callback which hits the /callback route in oauth-do, and is redirected back to the original domain:
• https://database.do/login/callback which hits the /login/callback route in oauth-do, which then generates the JWT token, and redirects the user back to:
• https://database.do/api which hits the /api route in database-do, except now, there is a cookie in the request header, which is then passed to the CTX service bindings on ctx-do, where the JWT token is verified and decrypted, and the user object is returned:
