$ haproxy -vv | grep -i options OPTIONS = USE_LINUX_SPLICE=1 USE_LIBCRYPT=1 USE_REGPARM=1 USE_PCRE=1 USE_STATIC_PCRE=1 You're using libpcre if USE_PCRE=1. You can check pcre regex with grep -P (it doesn't match on my machine): $ echo "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; GTB6.6; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET4.0C; .NET CLR 3.0.30729)" | grep -P 'test|android|avantgo|blackberry|blazer|compal|elaine| fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge\ |maemo|midp|mmp|opera\ m(ob|in)i|palm(\os)?|phone|p(ixi|re)\/|plucker|pocket|psp|symbian|treo|up\. (browser|link)|vodafone|wap|windows\ (ce|phone)|xda|xiino' $ echo $? 1 Best regards, Brane
