This site implementation did not allow me to redirect to my thank you
page and I was not receiving the form data. I used this implementation
and in 10 mins I had Capthcha and I received my data and the thank you
page redirects correctly.

Seems to be PROMOTION of your service, cause

1. Protectwebform has 2 implementations.

2. There is main installation which does not do any redirects! So your
post is incorrect at all.

3. The gateway installation redirects if only your site redirects, but
does it due to http protocol standards, and most of sites are written
not correct.

See: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
"Note: RFC 1945 and RFC 2068 specify that the client is not allowed to
change the method on the redirected request."

E.g. most sites use 302 to redirect to thankyou.html
Most browsers will not send the POST request, again to thankyou.html
but they should.
This would cause server error, "method not allowed".

Section "RFC 10.3.3" says that one should use
303 in this case.

This is the only reason why people have errors installing gateway
captcha.
