In the CGI Directory text field, type the directory to chdir to after chroot but before execution begins.
(UNIX only) In the CGI Nice text field, type an increment that determines the CGI program’s priority relative to the server. Typically, the server is run with a nice value of 0 and the nice increment would be between 0 (the CGI program runs at same priority as server) and 19 (the CGI program runs at much lower priority than server). It is recommended that you do not increase the priority of the CGI program above that of the server by specifying a nice increment of -1.
In the Chroot Directory text field, type the directory to chroot to before execution begins.
