Subj : Sending message to user from protocol

I'm working on a bash script to generate a URL to download a requested file via http which can then work as a protocol.

All of it works, except for sending a message back to the user. I know very little about socket programming, would this involve the socket passed via the %h parameter?

I tried something similar to:

echo -e "test message\n" | netcat $1 $2

Where $1 and $2 map to %i %h (client ip, socket descriptor). But I don't see anything on the client's end.
