squid 3.1.8 如何支持http1.1

squid 3.1.8 如何支持http1.1之前用的是squid2.6，但是对http11 支持不好，虽然squid2.7 设置参数可以支持http11，但是这些都是部分的。
看了下squid版本之间的对比，说squid3.0.xx 以上对http11完美支持。
squid3.0 添加httpd_accel_uses_host_header on //设定http1.1协议支持 应该可以，我没测过，既然选择选择个高点版本，要不就推荐使用2.7.

           我采用squid3.1.8 虽然默认支持http11. 但是我获取header头信息还是http1.0，
  
几个对http11相关说明的参数有：
#  TAG: vary_ignore_expire      on|off
#       Many HTTP servers supporting Vary gives such objects
#       immediate expiry time with no cache-control header
#       when requested by a HTTP/1.0 client. This option
#       enables Squid to ignore such expiry times until
#       HTTP/1.1 is fully implemented.
#
#       WARNING: If turned on this may eventually cause some
#       varying objects not intended for caching to get cached.
#Default:
# vary_ignore_expire off
#  TAG: via     on|off
#       If set (default), Squid will include a Via header in requests and
#       replies as required by RFC2616.
#Default:
# via on

还有其他几个参数和后端服务有关的keepalive

但我获取的信息一致都是1.0
如：
响应头

请教squid3.1.x 对http11 支持如何进行设置！！

问题继续跟踪中，继续翻阅资料，并希望大家能提供一些建议。
 
进展1：修改源码
    我试着将src 下关于http协议的源码由http1.0 都改为http1.1 重新编译安装，效果一样。待续。。
