Rails - Mar 2006 - Returning from Ajax call - "redirect_to error"

I have Ajax commenting on my site, well, I''m trying to get it working. 
It worked fine locally, but when I posted to the server, I''m getting an
"Application Error (Rails)", and I checked the logs, and it has:

(stack trace too deep)
/usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/base.rb:447:in
`url_for''
   
/usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/base.rb:769:in
`redirect_to''
/usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/base.rb:769:in
`redirect_to''
/usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/base.rb:769:in
`redirect_to''
/usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/base.rb:769:in
`redirect_to''
...
...

With the second line continuing forever.  Here''s my controller:

#controller
def comments
    content = Content.find(params[:id])
    @comment = Comment.new(params[:comment])
    content.comments << @comment
    content.save
    @comment.save
    @comment_count = Comment.count("content_id=#{params[:id]}")
    render_without_layout
end

#remote form
<%= form_remote_tag(
          :url => {:controller => ''inventory'', :action
=> ''comments'',
:id => content.id},
          :update => {:success => "new-comment"},
          :loading => "Element.show(''loading'');",
          :success => "Element.hide(''loading'');",
          :complete => "clearText();",
          :position => "bottom"
          ) %>

     <p>Name:<br/>
     <%= text_field "comment", "name", :size =>
"20" %></p>

     <p>Site:<br/>
     <%= text_field "comment", "site", :size =>
"20" %></p>

     <p>Remark:<br/>
     <%= text_area "comment", "entry", :rows =>
"7", :cols => "35"%></p>

     <p><input type="submit" name="submit"
id="form-submit-button"
value="Post Remark" class="btn" /><img
id="loading"
src="../../../../../images/loading.gif" alt=""
style="display: none;"
/></p>

     <div class="cmnt-rss"><a
href="/new/commentsfeed/" title="Syndicate
Comments (RSS 2.0)"><img
src="../../../../../images/rss_g.png" alt="RSS
2.0" /></a></div>

    <%= end_form_tag %>

Can someone please help with this?  Why is ''url_for'' used? 
What does it
do, and should I be using it?

Please help!  This is running live, and I can''t fix it!

Thanks for any advice.
