title: Send querystring params as part of form post
body: <p>Is there a way to capture the querystring and send that along as part of a form post? I'm using Rails 2.3.5 and my user is on a page that has multiple querystring parameters. On this page, they are going to submit a form. Inside the action that receives the post, I want to know what those querystring parameters were. Obviously, they are not sent as part of the post. So I need the actual form values, plus the querystring params that were on the page when the user submitted the form.</p>
  
  <p>I'm sure I could write some nasty javascript that would shove the querystring params into hidden fields on the form so they would be available, but that seems ugly. My Googling hasn't turned up much, which makes me wonder if I'm just going about this all wrong. To make matters worse, I'm a Rails newbie.</p>
  
  <p>Appreciate any pointers or ideas to get me going in the right direction.</p>
