what this cryptic names means? I did not find it in the manual nor in this forum.
These are internal references to objects managed by the FastCGI subsystem during its operation.
SUID: Server ID - This is the FastCGI server ID - You can have several FastCGI servers running at the same time - each bound to a particular interpreter.
PUID: Process ID - A FastCGI server will spawn one or more interpreter processes during its lifetime.
RUID: Request ID - The ID of a request processed by the process #PUID on FastCGI server #SUID.
The tuple (SUID, PUID, RUID) can be used to track a given request processing inside fastcgi.log.
