policy_module(apache, 2.2.0)

#
# NOTES:
#  This policy will work with SUEXEC enabled as part of the Apache
#  configuration. However, the user CGI scripts will run under the
#  system_u:system_r:httpd_user_script_t.
#
#  The user CGI scripts must be labeled with the httpd_user_script_exec_t
#  type, and the directory containing the scripts should also be labeled
#  with these types. This policy allows the user role to perform that
#  relabeling. If it is desired that only admin role should be able to relabel
#  the user CGI scripts, then relabel rule for user roles should be removed.
