@ -94,6 +94,10 @@ MDNS is used to resolve [`circuitpython.local`](http://circuitpython.local) to a
hostname of the form `cpy-XXXXXX.local`. The `XXXXXX` is based on network MAC address. The device
also provides the MDNS service with service type `_circuitpython` and protocol `_tcp`.
Since port 80 (or the port assigned to `CIRCUITPY_WEB_API_PORT`) is used for MDNS, the `mdns`
[module](https://docs.circuitpython.org/en/latest/shared-bindings/mdns/index.html#mdns.Server.advertise_service)
can't also advertise a service on that port.
### HTTP
The web server is HTTP 1.1 and may use chunked responses so that it doesn't need to precompute
content length.
