I'm using the Webform module in a Drupal 6 installation. This webform is appearing in an iFrame, and can be found on every page. The website that contains the iframe is static, the Drupal installation with the Webform module is the only thing being loaded in the iframe. This webform is a quiz with 20 questions. The rest of the site is kind of like a handbook, and I want my users to be able to use the static handbook website as a guide while taking the quiz. Each quiz question is on its own page; I am using webform's pagebreaks to split each question up.
Is there a way to set a cookie that takes the user back to the question they left off at, should they choose to leave the form and return?
