POSTing to a different website in a controller action

I have a page that has form that I want to submit to one of my
actions. However, inside of the action, I want to post to a different
website and have the browser go to that website.

The code I found on the groups seems to indicate I should do something
like the following. However, when I do the POST, I only see raw html
in the browser. Anyone have a suggestion on how to do this?

Here's the action in my controller:

  def pre_place_order
    parameters = Hash.new
    parameters['business'] = Variable::paypal_business_account
    parameters['upload'] = "1"
    parameters['cmd'] = "_cart"
    parameters['redirect_cmd'] = "_xclick"
    parameters['return'] = "http://#{Variable::server_hostname}/
place_order"

    idx = 0
    for item in @cart.shopping_cart_items do
      idx += 1
      parameters['item_name_#{idx}'] = item.product.name
      parameters['item_number_#{idx}'] = item.product.id.to_s
      parameters['amount_#{idx}'] = item.product.price. to_s

       if item.ship then
        parameters['shipping_#{idx}'] =
item.product.shipping_cost
       end
    end

    uri = URI.parse(Variable::paypal_transaction_url)
    http = Net::HTTP.new(uri.host)
    headers, res = http.post(uri.path, parameters)
    render res
end

Thanks,

Scott

Try

render :text => res

you might also set the content type to text/html…
