Recaptcha configuration and test

[rbrunetti]

Hello.
I'm trying to configure and test the recaptcha feature in a LiteSpeed Web Server Enterprise 6.0 following this guide:
https://blog.litespeedtech.com/2019/03/18/recaptcha-server-wide-protection/

According to the mentioned formula, the recaptcha should trigger when:

Active connections * 100 / Max Connections > (100 – Trigger Sensitivity)

The problem is that I' don't understand which configuration parameter Max Connections refers to:

- Configuration -> Server -> Tuning -> Max Connections/Max SSL Connections ??
- Configuration -> Server -> General -> PHP suEXEC Max Conn ??

I tried to put:
Configuration -> Server -> Security -> Enable reCAPTCHA = Yes
Configuration -> Server -> Security -> Trigger Sensitivty = 20
Configuration -> Server -> Tuning -> Max Connections/Max SSL Connections = 10
Configuration -> Server -> General -> PHP suEXEC Max Conn = 10
and in the site virtual-host:

<IfModule Litespeed>
  LSPHP_Workers 20
</IfModule>

then I fired up "ab" and made many concurrent requests of a php script.
I was not able to trigger the recaptcha page even if I could see many running requests, as can be seen by the attached screenshot.

What am I doing wrong?
Thanks a lot
Riccardo
