Apache Reference: mod_cgi, ScriptLog
Error Log File for CGI Scripts
Syntax: ScriptLog A
Example: ScriptLog logs/script_log
Since: Apache 1.2
This directive sets the error log file for CGI scripts. Without
this directive, no error logging is done. With it, given, any
output to stderr of the CGI scripts is logged into filename.
If this argument is a relative path name, it is taken as being
relative to ServerRoot. The log file will be opened as the
user run as the CGI child processes - that is, the user specified
in the main User directive. Consequently,This means that
either the directory containing the filename must be writable
by that user or the file must be manually created and set to
be writable by that user. Note that script logging is meant to
serve as a debugging feature when you are writing CGI scripts;
it should not be activated continuously on running servers.
