新上线的系统中IHS的error log发现很多Invalid method in request的报错。
[Thu Jan 16 00:02:59 2014] [error] [client 112.××.×××.×××] Invalid method in request \x16\x03\x01

在access log里面发现很大量大501报错

经过wireshark抓包发现，配置F5的工程师把提供http服务端80端口和提供https的443端口统一放到https的pool里面。这个配置使F5把https的请求发送到IHS服务器上的http的端口，导致报错的发生。这个报错可以通过浏览器用https协议访问http的端口重现。（https://192.168.0.100:80/）
