During one of my controller actions I want to call an external machine
before I do anything. It’s not a real web service, more like a
REST-style thing where I’ll just be tweaking a servlet running on
another machine and sending it some data.
Does Rails give me anything to work with for doing that? I read the web
service stuff but it’s overkill for what I need. I just need to open up
an http connection, send some data, and then check to see what response
I got back.
