Best Practice for captcha based protection against D.O.S to Nginx Proxy [duplicate]

  • 772

The idea is explained here

In simple words, Nginx Proxy plays the role of load balance and transmits the HTTP/HTTPS requests to servers.

If the number of request times within a certain period from an individual IP exceeds a threshold, it will trigger a captcha for the upcoming requests.

And the end-user must input the correct captcha code before he can continue to access the site.

Do you know any open source / free NGINX module for this usage? I searched on the Internet and here is one of them: https://github.com/snbuback/nginx seems it needs modification.

Any suggestion / experience is welcome, thank you

    I think, captcha will only annoy your real users. For this problem I'd rather use the testcookie-nginx-module.
