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
