Returning a response with Ruby CGI before script is finished? -

-

anyone know how send cgi response in ruby before cgi script finished executing?

i'm creating fire-and-forget http api. want client push data me via http , have response return successfully, , then swizzles data , processing (without client having wait response).

i've tried several things don't work, including fork. following wait 5 seconds when invoked via http.

#!/usr/bin/ruby  require 'cgi'  cgi = cgi.new cgi.out "text/plain"   "1" end  pid = fork if pid   # parent   process.detach pid else   # child   sleep 5  end

i answered own question. turns out need close $stdin, $stdout, , $stderr in child process:

#!/usr/bin/ruby  require 'cgi'  cgi = cgi.new cgi.out "text/plain"   "1" end  pid = fork if pid   # parent   process.detach pid else   # child   $stdin.close   $stdout.close   $stderr.close   sleep 5  end
