This is a modified version of HTTPD, packaged for Debian.
This version of HTTPD is from 1994, and will obviously not support any modern HTTP features (HTTP/1.1+, Content Negotation, etc.) and will have countless security issues and exploits.
I would recommened using NGINX as a reverse proxy in-front of this server, with Fail2Ban configured very strictly to prevent any chance of exploits reaching the server.
Head to the releases page and download httpd.deb.
Once installed, run systemctl enable --now httpd to start httpd on boot,
Or run httpd -v -p 8080 for testing.
Building is as simple as running these two commands
make all
make install
Once finished, there will be a httpd.deb file you can install on any 64-bit Debian system.
