Mongrel2, a short introduction
Mongrel2 is a language-agnostic web server that focuses on HTTP protocols and can be used with various programming languages. Its configuration is managed through a SQLite3 database and allows for dynamic management of server processes and handlers using the m2sh command-line tool. The server facilitates asynchronous request handling through ØMQ sockets, significantly enhancing performance and scalability.
