Filling Out the Form: Custom Unprimer Variables

Sometimes submitting the form directly is not sufficient. Forms on web pages can contain dynamic hidden variables, such as a viewstate for session tracking. This means the form must be opened, filled out, and submitted, instead of simply submitting a pre-defined action URL.

This is achievable with the Custom Unprimer Variables setting. Instead of setting Custom Unprimer URL to the action of the form, you set it to the URL of the page that contains the form. Custom Unprimer Variables is a URL-encoded list of name/value pairs to set on the Custom Unprimer URL page.

When Custom Unprimer Variables is set, the Custom Unprimer URL is fetched, and then the variables specified in Custom Unprimer Variables are used on the form, and then that form is submitted.

Webinator will set the HTTP(S) Referer header for each unprimer URL to the URL of the previously URL so systems that require Referers will work. If the first unprimer URL also requires a Referer add an unprimer URL before that so it picks up that as the Referer. This does not affect the use of Referer in the main walk.
