Original Pull Request: https://github.com/ADD-SP/ngx_waf/pull/140

State: open
Merged: No

Summary

This module needs to send HTTP requests to the CAPTCHA server to verify if the CAPTCHA passes. Currently, this was done by the libcurl, but this blocks the event loop of the Nginx, so replacing it with subrequests is more efficient.
