spawn-fcgi is used to spawn remote and local FastCGI processes.
Until recently, it was part of the lighttpd project, but has been
unhinged into its own projects some weeks ago. Because of this, I have
made some efforts to include it into pkgsrc as its own package.
Here the official statement from the project-website about spawn-fcgi:
While it is obviously needed to spawn remote FastCGI backends (the web
server can only spawn local ones), it is recommended to spawn local
backends with spawn-fcgi, too.
Reasons why you may want to use spawn-fcgi instead of something else:
* Privilege separation without needing a suid-binary or running a
server as root.
* You can restart your web server and the FastCGI applications without
restarting the others.
* You can run them in different chroot()s.
* Running your FastCGI applications doesn't depend on the web server
you are running, which allows for easier testing of other web
servers.
