jsurinx on "[Plugin: Contact Form 7] Adding parameters in the "Thank You" Url?"

Hi there,

I'd like to add parameters like

&language=NL
&last=lastname
&first=firtname

In my URL for a 3rd party program...

Any idea how I could customize this additional code?

on_sent_ok: "location = 'http://musite.com/';"

Many thanks!
Jonathan
