ats ChangeLog 跟进
ATS 4.1.0 (Note)
添加 .include 指令
remap.config 配置如下：
.include /etc/trafficserver/baidu.conf
baidu.conf 配置如下：(和正常remap中的规则一样)
map http://www.baidu.com/ http://www.baidu.com/
traffic_line -x 生效
BTW: 如果只改变baidu.conf 内容，traffic_line -x 则不生效，只有改变remap.conf
的修改时间才会生效。最有效的办法是 touch /etc/trafficserver/remap.conf
然后再执行traffic_line -x
删除不用的日志字段
prob
prcb
cgid
CONFIG proxy.config.log.custom_logs_enabled INT 1 配置customlog 的时候注意不能再引用这些字段 ()
增加4个 cache 控制项（解决内容重复缓存 --->content duplications in cache）
建议值为2 (安全选项，如果对自己的内容有更好的把握，可以设置为1 比如图片类的应用)
proxy.config.http.cache.ignore_accept_mismatch
Scope: CONFIG
Type: INT
Default: 0
Reloadable: Yes
When with a value of 1, Traffic Server serves documents from cache with a Content-Type: header that does not match the Accept: header of the request. If set to 2, this logic only happens in the absence of a Vary header in the cached response (which is the recommended and safe use).
Note This option should only be enabled with 1 if you’re having problems with caching and you origin server doesn’t set the Vary header. Alternatively, if the origin is incorrectly setting Vary: Accept or doesn’t respond with 406 (Not Acceptable), you can also enable this configuration with a `1.
proxy.config.http.cache.ignore_accept_language_mismatch
Scope: CONFIG
Type: INT
Default: 0
Reloadable: Yes
When enabled with a value of 1, Traffic Server serves documents from cache with a Content-Language: header that does not match the Accept-Language: header of the request. If set to 2, this logic only happens in the absence of a Vary header in the cached response (which is the recommended and safe use).
Note This option should only be enabled with 1 if you’re having problems with caching and you origin server doesn’t set the Vary header. Alternatively, if the origin is incorrectly setting Vary: Accept-Language or doesn’t respond with 406 (Not Acceptable), you can also enable this configuration with a `1.
proxy.config.http.cache.ignore_accept_encoding_mismatch
Scope: CONFIG
Type: INT
Default: 0
Reloadable: Yes
When enabled with a value of 1, Traffic Server serves documents from cache with a Content-Encoding: header that does not match the Accept-Encoding: header of the request. If set to 2, this logic only happens in the absence of a Vary header in the cached response (which is the recommended and safe use).
Note This option should only be enabled with 1 if you’re having problems with caching and you origin server doesn’t set the Vary header.

proxy.config.http.cache.ignore_accept_charset_mismatch
Scope: CONFIG
Type: INT
Default: 0
Reloadable: Yes
When enabled with a value of 1, Traffic Server serves documents from cache with a Content-Type: header that does not match the Accept-Charset: header of the request. If set to 2, this logic only happens in the absence of a Vary header in the cached response (which is the recommended and safe use).

日志系统冗余备份
使用 '|' 分割 在 logs_xml.config.
<CollationHosts = "host1:5000|host2:5000|host3:6000, 209.131.52.129:6000"/>
当host1 挂掉，则使用host2 和host 3做为备份，日志会传到host2 如果host2 也挂掉，则传到host3
直到host1 或host2 正常为止。
<CollationHosts = "host1|host2|host3, host4|host5">
两组日志服务器 (host1|host2|host3)和 (host4|host5)
host2/host3 是host1的备份
host5 是host4的备份
所有的日志都会传到两组服务器中去，而两组服务器中，只会选择第一个链接的服务器做为传输机器。
支持多条后缀规则
dest_domain=www.test.com suffix=jpeg,js,css,html,bc,bd ttl-in-cache=1m
支持* 匹配
dest_domain=www.test.com suffix=* ttl-in-cache=1m
