Why doesn't jQuery.parseJSON() work on all servers?

Question

Hey there, I have an Arabic contact script that uses Ajax to retrieve a response from the server after filling the form.

On some apache servers, jQuery.parseJS

Answer 1

I don't see anything related to parseJSON()

The only difference I see is that in the working example a session-cookie is set(guess it is needed for the "captcha", the mathematical calculation), in the other example no session-cookie is set. So maybe the comparision of the calculation-result fails without the session-cookie.
