27+1. Any request passing through the proxy (and not matched by `--skip-auth-regex`) is checked for the proxy's session cookie (`--cookie-name`) (or, if allowed, a JWT token - see `--skip-jwt-bearer-tokens`).
28+2. If authentication is required but missing then the user is asked to log in and redirected to the authentication provider (unless it is an Ajax request, i.e. one with `Accept: application/json`, in which case 401 Unauthorized is returned)
29+3. After returning from the authentication provider, the oauth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set
30+4. The request is forwarded to the upstream server with added user info and authentication headers (depending on the configuration)
32+Notice that the proxy also provides a number of useful [endpoints](/oauth2-proxy/endpoints).
