I don't think it's a YAML problem. Show us the code where you go from
your YAML configuration to instantiating agent_host and agent_port in
the url assignment:

> url = "http://#{agent_host}:#{agent_port}/home/create_unit?"

BTW, I think you'd might be better off constructing the url via the
URI library. It makes things a bit less error prone and can do nice
things like check the validity of the url syntax and such.
