What kind of detection does the script do?

Do you mean "refresh" by "push" ?

 |But this push needs access to the origin server and to the delegate .

How do you access to the origin server?  Anyway, I think you need
to access to the origin server to detect modifications.

But you need not to restart DeleGate to refresh a directory cache.
A special FTP command "CWD .", which is issued by "cd ." command in
in usual ftp clients, disables reading cache (toggle).  So a command
sequence "cd ." and "ls -l" will refresh the directory cache.
