This is the same as the minimal http server, with one difference... if you connect to localhost:7681 with something that doesn't send recognizable http, then the connection will be switched to a raw-skt role and bind to a protocol that echoes anything sent back to the sender.
$ cmake . && make
| Commandline option | Meaning |
|---|---|
| -d | Debug verbosity in decimal, eg, -d15 |
| -s | Configure the server for tls / https and LWS_SERVER_OPTION_ALLOW_NON_SSL_ON_SSL_PORT |
| -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) |
| -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. |

This allows testing of various combinations of special features for unexpected content on an http(s) listening socket.
