submitting a GET form with query string params and hidden params disappear

Question

Consider this form:

Answer 1

I had a very similar problem where for the form action, I had something like:

The button would get the user to the site, but the query info disappeared so the user landed on the home page rather than the desired content page. The solution in my case was to find out how to code the URL without the query that would get the user to the desired page. In this case my target was a Drupal site, so as it turned out /content/something also worked. I also could have used a node number (i.e. /node/123).
