title: Rails redirect without changing URL
body: <p>I've some piece of ruby/rails code. </p>
  
  <p>In one of the controllers say foo i have an action doo which does something and I want to redirect to another controller say bar and action say dar. </p>
  
  <p>When I use redirect_to then URL in the address bar changes to /bar/dar while if I use render then I don't know how to render another controller's view. </p>
  
  <p>I am using rails 2.3.5 so render_component is unavailable for use (which i found could be really really useful for me) -- so as a shortcut if you have any idea of alternate for render_component that will help me infinitely. </p>
  
  <p>Any ideas? </p>
  
  <p>[If am unclear please ask me details]</p>
