title: Rails HTTP Basic Authentication Failure
body: <p>I'm trying to use authenticate_with_http_basic in a Rails 2.3.4 app, and the username and password aren't being picked up. I did a little detective work and figured out that it's failing because there's no authorization header in the request. I tried adding the RewriteRule suggested in the docs:</p>
  
  <pre><code>RewriteRule ^(.*)$ dispatch.fcgi [E=X-HTTP_AUTHORIZATION:%{HTTP:Authorization},QSA,L]
  </code></pre>
  
  <p>I haven't had any luck, though, either with Apache/Passenger or Mongrel. I also didn't have any luck trying authenticate_with_http_basic in a Rails 3 app. If I change it to authenticate_or_request_with_http_basic, credentials given at the prompt work, but it ignores any supplied in the url. (Which makes sense, since it's calling authenticate_with_http_basic.) I can't find anything in my code that should be messing with the request, and it seems odd to me that it isn't working locally with Mongrel. Any suggestions?</p>
