"I hear the excuse, "it uses too much CPU time", but this is often from people who have written their web applications in Ruby"<p>I'm curious about this, are these excuses you've heard based on configurations where a proxy server processes the initial https req and then sends the backend request encrypted, too? This is where Ruby is handling an encrypted request?<p>Or are you saying there are people who have excused https from their setup because their frontend web server is written in Ruby?
