CVS log for validator/htdocs/no_referer.asis

Request diff between arbitrary revisions

HTTP status code sent for no-referer response to /check/referer (ab)used 412 precondition
failed, when there was actually no client precondition set. Using 403 instead, consistent
with what we do on CSS validator, and probably better understood by bots responsible
for this traffic than 412.

preparing 0.8.1, changelog and version bump

Bad bots keep calling /check/referer without referer, kicking check into
action for nothing. Performance-wise, it's probably wiser to catch these
at apache level, with e.g:

#do not pass /check/referrer on if there is no referrer
RewriteCond     %{REQUEST_URI}  ^\/check\/referer
RewriteCond     %{HTTP_REFERER} ^$
RewriteRule     ^               /no_referer.asis [L]
