    If httpd scripts should be allowed to write to public directories you need to turn on the $BOOLEAN boolean and change the file context of the public directory to public_content_rw_t.  Read the httpd_selinux

    "setsebool -P $BOOLEAN=1; chcon -t public_content_rw_t <path>"
    You must also change the default file context labeling files on the system in order to preserve public directory labeling even on a full relabel.  "semanage fcontext -a -t public_content_rw_t <path>"
