render :file in another window

is there a way to render a file in another window

I wrote :
  def show
    @asset = Asset.find(params[:id])

    respond_to do |format|
      format.html
      format.xml { render :xml => @asset }
      format.pdf {render :file => @asset.data.path }
    end
  end

this render in the current window....

thanks for your suggestions

format.pdf {send_data(@asset, :filename => @asset.data.path, :type
=>'application/pdf',:disposition => 'inline') }

Thanks Sijo

I also found that I could use the :popup => true in the 'link_to'
