I am making an application to register accounts on a webpage. That webpage contains a field that's called ab_test_data, The content of a field will be generated when I click "Sign up" button, It's generated by a javascript function that does a sort of a complicated algorithm which I totally don't understand. I want to be able to understand what is A/B testing and how it's used as an Anti-bot technology. I would also want to understand how to bypass it if possible.
note: The questions assumes that I will be using HttpWebRequest/Response to send my data.
Thanks in advance.
A/B Testing is not specifically an anti-bot technology. However this may be the side-effect if the site is requiring that it contains the results of the A/B test.
A/B Testing is a way to test what impact specific changes have on your user's behaviour. For example, changing the way you lay out a product page and whether this improves sales.
Wikipedia has more information on A/B Testing
I would suggest altering the site behaviour so that you don't require the A/B Test data (or setting it to a known value) if you wish to automate your process.
