Thank you for posting patch so quickly.

Can confirm, 'return 200' actually works on 'nginx/1.23.1', my bad, sorry. Was also testing this issue on a different server with 'nginx/1.22.0' and 'return 200' does not work there.

Regarding the configuring error pages, I wanted to minimize server exposure and minimize resources spent on processing requests from scripts and scanners, especially to malformed ones, as there is absolutely no value in doing that.

Have not tested patched and recompiled nginx yet.

    1 **Problem**: when built-in error '400' redirected to custom handler, and used incorrect request method along with invalid/absent 'Host:' header, nginx does not perform any actions, just hangs keeping connection open.
