- CGI support is added to Nginx and Angie webservers, tested on various OS including Linux, Darwin, BSD, and Solaris.
- CGI is described as a tool with specific use cases: good for low frequency applications, resource-limited systems, low budget projects, and prototyping; bad for high QPS, high traffic, and high concurrency.
- A Discord channel is available for CGI enthusiasts, troubleshooting nginx-cgi, updates, and networking.
- Installation involves cloning the source, building a deb package, and enabling CGI in Nginx configuration.
- CGI scripts can be written in any language, with examples provided in shell scripting, including handling headers and body output.
- Advanced features include support for sudo, chroot, Docker, and FreeBSD jails for running CGI scripts in isolated environments.
- CGI scripts can handle streaming for both request and response bodies, with examples like an online calculator using `bc`.
- Configuration directives like `cgi_pass`, `cgi_interpreter`, and `cgi_strict` offer flexibility in how CGI scripts are executed and managed.
- Environment variables passed to CGI scripts include standard RFC3875 variables and additional non-standard ones for enhanced functionality.
- Security considerations are discussed, including the risks of running scripts with elevated permissions and alternatives like Docker for sandboxing.
