# This policy module provides support for mod_fcgid using the httpd system script domain.

# It provides "allow" rules that will overlap to varying degrees with selinux-policy

# packages for Fedora 5 onwards, and is a stepping stone to the merged policy included

# as updates for selinux-policy in Fedora 8, 9, and 10.

#

# Rules existing in selinux-policy 2.6.4 (F7) have been stripped from this policy

#

# Previous versions of this policy module used a separate domain, httpd_fastcgi_script_t,

# which is now an alias for httpd_sys_script_t.
