CGI File UID - works/how it works?

i am testing some configurations and i read:

"File UID, set user/group id of external application process based on the user/group id of the external application executable; "

i add lsapi and set command to my own php file with specific uid/gid

and php start with global uid, not with executable uid and not with docroot uid

Why it does not start ? Maybe i readied it wrong?

Thx for answer and help.

You need to set "ExtApp Set UID Mode" to "Doc Root UID"
http://www.litespeedtech.com/docs/webserver/config/vhostlist/#setUidMode

and define the external app at vhost level.

hmm...

i have external php in vhost level and i use "Doc Root UID" for about 1-2 year this option, but i need/want to spawn php with different uid/gid so i look and see

File UID

so i test it and it doesn't work .. or maybe am i some miss understanding ?

if i change to "Doc Root UID" it spawn with uid from directory, if i set to File UID or Server UID it spawn with "apache" (server uid)

its normal or this not working in free version of ls?

File UID option does not work with PHP. For PHP, only "Doc root UID" or "Server UID" will work.

so thats why it says "CGI File UID"

thanks for fast answer and your time
