Question

I am looking for possibility to have ruby-based webserver communicating by pipe, not by TCP/IP. So I will send HTTP request by pipe and I want to read response by pipe. It should be used as bundled/internal webserver (RPC or something) for desktop application. I don’t want to handle ports configuration when there will be more instances of my application running on same machine.

Any ideas?

Thank you in advance.

Try a UNIXSocket You use a local path to specify where the socket connection is, not a port, and you can easily handle multiple simultaneous connections.

# server.rb require 'socket' File.delete( filename ) if File.exists? filename server = UNIXServer.open( filename ) server.listen( queuesize )  puts 'waiting on client connection' while client= server.accept   puts 'got client connection #{client.inspect}'    child_pid = fork do      puts 'Asking the client what they want'     client.puts 'Welcome to your server, what can I get for you?'     until client.eof?       line = client.gets       puts 'The client wants #{line.chomp.inspect}'     end     client.close   end    puts 'running server (#{child_pid})'   client.close   Process.detach(child_pid) end  server.close   # client.rb require 'socket' puts 'requesting server connection' server = UNIXSocket.new( filename ) puts 'got server connection #{server}' line = server.gets puts 'The server said: #{line.chomp.inspect}' %w{ a-pony a-puppy a-kitten a-million-dollars }.each do |item|   server.puts item end server.close
