Rails - Jun 2009 - process request and redirect to another url with all params

I am trying to do the following:
process a request containing form data. Once I my app has successfully
completed its processing, I would like to redirect_to a totally
different site and pass along the parameters that came in with the
original request.

This is how I am currently handling it in the controller:
[code=]def create
      @subscription = Subscription.new(params[:subscription])

      @subscription.user_id = current_user.id

      @subscription.subscribe

      respond_to do |format|

          if @subscription.save
            parms2 = params

            format.html {redirect_to
"http://www.someothersite.com/process",parms2}
          else
           #handle the problem
          end
        end

      end[/code]
Everything up to the redirect is happening correctly. Then I am
redirected to www.someothersite.com but it is behaving as though the
parms2 are missing. I am new to Ruby and Rails and am probably missing
something very easy here.

Thanks in advance.

The key issue here is that this will need to be send as a POST request, 
whereas I assume the default of redirect_to is GET.

You will have to put the params onto to the end of the url string 
yourself, eg.

param1=this&param2=16&param3=that
