title: Rails authenticate_or_request_with_http_basic not working on SSL + Nginx
body: <p>I've get an action in my Rails 3 app that I'm pw-protecting with authenticate_or_request_with_http_basic. Working fine on my development machine but it's not prompting for the http_basic user/password on the production server. </p>
  
  <p>The entire production app runs over https/SSL on nginx. </p>
  
  <p>Where do I look to resolve this? Does http basic auth not work over SSL? Or is there an nginx setting I need to look at? </p>
  
  <p>TIA</p>
