redirect_to :action => ''list'' forces the clients browser to
request the
list action. 

render :action => ''list'' will render the template
list.rhtml without
calling or redirecting to the list action.

This causes an HTTP redirect to be returned to the browser,
which then fetches the new URL.
> 2) render :action => ''list''
This causes a ''server side'' redirect, and causes
the other action to be executed without the browser
knowing anything about the change.

That''s wrong. The action never gets called. Only the template for that
action is rendered.

Almost. The action is not executed, only the corresponding template  
list.rhtml is rendered as if the call was

    render :view => ''list'' # imaginary API

being equivalent to

    render :template => "#{controller_name}/list.rhtml"

modulus the template extension. It could even happen that the list  
action renders something else.

Server-side "redirects" are done with render_component.

Hmm, I never knew this... seems like an unfortunate decision, bound to create
confusion.

Thanks for the corrections, Xavier and Norman!

I hate it when I do that! :-)
