External link sends along session code

[maxblomberg]

Hi,

I noticed that formr automatically appends the session code when using the redirect (external link) module.

In my setup, I created a mailing study that only collects participants' email addresses and sends out invitation links. When participants click the login link in the email, they are redirected to the main study via the external link module (see below).

In the main study, participants identify themselves using a personal identifier set externally (not within formr). This setup is intended to separate email addresses (which often contain names) from the sensitive data collected in the main study.

However, because formr appends the session code to the redirect URL, the two studies are still linked.

Is there a way to suppress the session code from being passed along during the redirect?

Thanks in advance!

1. What you write is not correct. formr automatically replaces {{login_code}} with the code, but in your example, nothing is added to the URL. I think what the problem is in your case (on the outdated formr instance in Muenster) is that both runs/studies are on the same domain, so the same session cookie is reused. This will be different once the updated formr instance in Muenster goes live (soon!). So, then it will work as you expect.
2. I understand what you are trying to do. The feature I built specifically for this purpose is the concept of an "unlinked" survey. I.e. you collect the identifiable data in a survey and that survey is detached from the rest of the run/data. Might be more elegant and people don't need to identify themselves using a code, which I guarantee they will get wrong sometimes.

Thanks for the swift reply, Ruben. Looking forward to the new version, then!
