Как мне обрабатывать предупреждения apache2 modsecurity2, такие как соответствие «rx ^ OPTIONS $» и «REQUEST_METHOD»?

После обновления с squeeze до wheezy я получаю множество этих сообщений в моем журнале ошибок apache, когда я открываю веб-страницу на моем сервере (изменено на myserver.de Вот):

[Sat Oct 19 01:06:21 2013] [error] [client 213.239.220.106] ModSecurity: Warning. Match of "rx ^OPTIONS$" against "REQUEST_METHOD" required.

строки 40 и 41 в моем

/etc/apache2/modsecurity2/modsecurity_crs_21_protocol_anomalies.conf`:

выглядят так:

SecRule &REQUEST_HEADERS:Accept "@eq 0" \
    "chain,phase:2,skip:1,t:none,log,auditlog,msg:'Request Missing an Accept Header', severity:'2',id:'960015',tag:'PROTOCOL_VIOLATION/MISSING_HEADER'"

может ли это быть конфликтом с mod_pagespeed?

Обновление: я отключил mod_security, пока эта проблема не будет решена и предупреждения не исчезнут (как и ожидалось)
