I do not cleanup until the end and I only init once. I'm still not able to
get it to work without having the cookie stored in a file. The code will
run, but it doesn't actually update the form. Below I have my current code.
I have commented out the SSL flags as that is causing a different issue. I
tried not setting CURLOPT_COOKIEJAR, but it didn't help. I think I am
close, but not quite there.
