If someone indicates that they need socket server enabled server
What kind of server is that?
SSL ?

Probably...

SSL being Secure Socket Layer, it might be.
But a socket is a listener, in the network computer jargon.

You can have a program "listening" to a socket and another one talking to it.
It allows them to communicate via a sequence of write/read.

Or it can be a socks proxy server ...
The term "socket server enabled server" doesn't really means anything.

They just want to be plugged in, that's all

Can you please place more details to the request you have?

Socket type connection is a just like an internet protocol like http but the connection and request/reply are always active. There should be always a connection between the server and client. Servers that allows socket connection are mostly applicable to wireless communication.

Why just not ask clients what they are actually looking for?
