FastAGI doesn’t get (or deserve) much love these days but a lot of people are still widely using it. Here is a small project of mine, started trying to scratch my own itch, that some might find useful.
It is a reverse proxy for the FastAGI protocol with some interesting features. Most noticeably request based routing, HA/failover, load balancing and TLS encryption for FastAGI sessions (something asterisk unfortunately is still lacking). It is written in Go and it is quite fast and light on resources. First public release, feedback and patches are more than welcome 😉
