    MVProc FastCGI

    MVProc FastCGI

    MVProc implemented as a FastCGI

    MVProc FastCGI is a Model-View-Controller platform that uses MySQL stored procedures as the Controller element. It's based on the stable Apache module MVProc, and all functionality has been tested (and load tested), so it may be "Production Ready" even though it hasn't been implemented in a production environment as yet. Benchmarking indicates it's "nearly as fast" on lighttpd as the MVProc Apache module, though a truly thorough benchmarking with a variety of servers and web applications (outputting the same result) would be more than welcome if anyone is offering... It's fast and runs great on Lighttpd! Supports application/x-www-form-urlencoded and multipart/form-data! Highly configurable! Very fast templating! Designed to be secure, with SQL injection protection, XSS attack protection, and more! Responsive project admin!
