Features

• Takes a configuration file as argument, or use a default path.

• Supports GET, POST, and DELETE methods.
• Stress-tested and stays available at all costs.

• Setup server names or not.
• First server for a host:port is the default for that host:port.
• Setup default error pages.
• Limit client body size.
• Setup routes with rules/configuration:
  • List of accepted HTTP methods for the route.
  • HTTP redirection.
  • Turn directory listing on or off.
  • Default file to answer if request is a directory.
  • Execute CGI based on file extension (for example .php).
  • Route able to accept uploaded files and configure where to save them.

    Location /uploads/ {
        client_max_body_size 100b;
        root var/localhost;
        autoindex on;
    }

    Location /cgi-bin/ {
        limit_except GET;
        error_pages 404 error_pages/4040.html
        autoindex on;
    }

    Location /developer_files/ {
        return 403 error_pages/403.html;
    }

    Location / {
        limit_except GET;
        root var/localhost/files;
        index lol.html;
    }

    Location /error_pages/ {
        limit_except GET;
        autoindex on;
    }
}

## CGI
- The server calls the CGI with the requested file as the first argument.
- The CGI is run in the correct directory for relative path file access.
