B.10.1. Apache::RefererBlock—Block Request Based Upon "Referer" Header
Apache::RefererBlock will examine
each
request. If the MIME type of the
requested file is one of those listed in
RefBlockMimeTypes, it will check the
request's Referer header. If the
referrer starts with one of the strings listed in
RefBlockAllowed, access is granted. Otherwise, if
there's a RefBlockRedirect
directive for the referrer, a redirect is issued. If not, a
"Forbidden" (403) error is
returned.
Available from CPAN. See the module manpage for more information.
