PATH_INFO
Description: Path information
Syntax: PATH_INFO
PATH_INFO contains additional path information after the file path in the URL and before the query string. For example, for /cgi-bin/script.py/extra/path, PATH_INFO’s value is /extra/path. In RESTful APIs, this variable may contain routing parameters.
Example:
# Detect directory traversal in PATH_INFO
SecRule PATH_INFO "@contains .." \
"id:1040,phase:1,deny,msg:'Directory traversal detected in PATH_INFO'"
