1# lws minimal raw fallback http server
2
3This is the same as the minimal http server, with one difference...
4if you connect to localhost:7681 with something that doesn't send
5recognizable http, then the connection will be switched to a
6raw-skt role and bind to a protocol that echoes anything sent back
7to the sender.

19-d <loglevel>|Debug verbosity in decimal, eg, -d15
20-s|Configure the server for tls / https and `LWS_SERVER_OPTION_ALLOW_NON_SSL_ON_SSL_PORT`
21-h|(needs -s) Configure the vhost also for `LWS_SERVER_OPTION_ALLOW_HTTP_ON_HTTPS_LISTENER`, allowing http service on tls port (caution... it's insecure then)
22-u|(needs -s) Configure the vhost also for `LWS_SERVER_OPTION_REDIRECT_HTTP_TO_HTTPS`, so the server issues a redirect to https to clients that attempt to connect to a server configured for tls with http.
