reason? because that is the way it was designed to be.
"requests shall come from clients when HTTP is happening"
"replies shall come from servers when HTTP is happening"
no less fundamental principles than:
"rain shall come from the sky when gravity is happening"
Other designs have other names. This is HTTP design.
You can be a server "by hand". Open a socket and listen on it until
somebody (squid) connects and hands you a request for data. You then
send the reply for that requested URL.
