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])

  @subscription.user_id =


  respond_to do |format|

        parms2 = params

        format.html {redirect_to”,parms2}
#handle the problem


Everything up to the redirect is happening correctly. Then I am
redirected to 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.
