H2S90: How to identify the correct scheme for a web.socket-conn:

Hu: http://, ws://, vs tcp://

H3S1: PHP-testing:

H4S1: HTTP.client-test,int.server-2

tcp:// worked to establish socket_server, and socket_client, whereas neither ws:// nor http:// worked as well, in our initial 11/5/22 test.

H4: Suspend. We will suspend update on this note, for now. Fin.v-1<fbno>
