Redirect action on included form

Hey there,

I'm having issues with getting my form to redirect to the correct page.

The default route for the form is /forms/growth-form.

However, I'm not accessing it directly, but including it in my Twig Template using:

{% include "forms/form.html.twig" with { form: forms('growthform') } %}

The page is being accessed through the route mysite.com/3/c:client/l:location where client and location are variables.

I'd like to redirect to mysite.com/thank-you/3/c:client/l:location, but I can't seem to get pass the uri.param() variables to the new URL.

Any ideas on what the best way to get achieve this would be?

Thanks
