Irule recaptcha China

Hi Everyone,

 

I have an application that integrates correctly with Google reCAPTCHA, the problem is I need the reCAPTCHA to be accessible within China, as a workaround I have written a basic HTTP stream irule but the problem is the solution is unstable, for example, we have the following issue

 

It takes a user about 8 to 15 verify requests before the user's response is accepted within the Recaptcha interface. When using the google domain I receive a successful response within three requests.

 

I'm currently investigating the response from Google but I'm wondering if anyone else has written a similar solution without using "Google reCAPTCHA v2 challenge iRule". I have a funny feeling the problem is related to the session but any tips would be great.

 

Setup - 2 Vips to support "google.com" / "; - Streaming Irule

 

Next week I'm going to look into my VIP configuration further and base it on (https://devcentral.f5.com/articles/google-recaptcha-v2-challenge-irule-integration-with-bigip-virtual-server-24369)
