Is your feature request related to a problem? Please describe.

AWS allows only wss and not ws. WSS is not just secure, it is better because the ISPs and gateways won't block wss traffic as they don't see it

Describe the solution that you would like.

Provide wss support in gorilla-websocket implementation, or guide/point me so I can help add

Describe alternatives you have considered.

The package supports WSS clients and servers.

To dial a connection using WSS, specify "wss" as the URL scheme. Search for "wss" in client.go to find the relevant code.

To handle WSS connections on the server, register your websocket endpoint with an HTTP server listening for HTTPS connections. There is no code in the repository specific to serving WSS connections because TLS is handled by the HTTP server.

Changes to echo example for using TLS.

Set TLS port (and use all interfaces if wanted).

var addr = flag.String("addr", ":443", "https service address")

Use wss.

homeTemplate.Execute(w, "wss://"+r.Host+"/echo")

Serve TLS with certificate and key.

log.Fatal(http.ListenAndServeTLS(*addr, "server.crt", "server.key", nil))

Generate certificates for testing.
openssl genrsa -out server.key 2048
openssl req -new -x509 -sha256 -key server.key -out server.crt -days 365

Cloudflare example for production.
Add a proxied DNS record for the domain. Create the certificate and key for it under SSL/TLS -> Origin Server.
