} 4. 测试
没有做缓存状态:
有做缓存状态:
5. 响应头状态
第一次请求:
再次请求:
6. 查看redis是否缓存以及过期时间
PS:srcache-nginx-module模块指令说明:
srcache_fetch
语法:srcache_fetch <method> <uri> <args>?
默认值:no
配置段:http, server, location, location if
查询缓存。返回200说明缓存命中,直接从缓存响应客户端请求。非200需要后端程序处理。
srcache_fetch_skip
语法:srcache_fetch_skip <flag>
默认值:srcache_fetch_skip 0
配置段:http, server, location, location if
<flag>支持nginx变量。当这个参数值不为空和不等于0,则从缓存取数据过程被无条件跳过。
srcache_store
语法:srcache_store <method> <uri> <args>?
默认值:no
配置段:http, server, location, location if
将当前请求的响应存入缓存。可以使用srcache_store_skip和srcache_store_max_size指令禁用缓存。不管是响应状态行,响应头,响应体都会被缓存。默认情况下,下列特殊响应头不会被缓存:
- Connection
- Keep-Alive
- Proxy-Authenticate
- Proxy-Authorization
- TE
- Trailers
- Transfer-Encoding
- Upgrade
- Set-Cookie
可以使用srcache_store_pass_header、srcache_store_hide_header指令来控制哪些头要缓存哪些不要。
注意:即使所有的响应数据被立即发送,当前的nginx请求生命周期未必完成,直到srcache_store子请求完成。这意味着服务器端延迟关闭TCP连接,或下一个请求服务发送同一个TCP连接。
srcache_store_max_size
语法:srcache_store_max_size <size>
默认值:srcache_store_max_size 0
配置段:http, server, location, location if
当响应体超过该值,将不会缓存。
当后端缓存存储有对缓存数据做硬限制,这个指令非常有用。比如memcached服务器,上限是1M。
默认值0,不限制。
srcache_store_skip
语法:srcache_store_skip <flag>
默认值:srcache_store_skip 0
配置段:http, server, location, location if
<flag>支持nginx变量。当这个参数值不为空和不等于0,则从存入缓存过程被无条件跳过。
srcache_store_statuses
语法:srcache_store_statuses <status1> <status2> ..
默认值:srcache_store_statuses 200 301 302
配置段:http, server, location, location if
该指令控制那些状态码响应被缓存。
srcache_header_buffer_size
语法:srcache_header_buffer_size <size>
默认值:srcache_header_buffer_size 4k/8k
配置段:http, server, location, location if
在序列化响应头时控制头缓冲大小。默认大小为页面大小,通常为4k或8k,取决于具体平台。
注意:该大小是以每个头的,因此,需要足够大来容纳最大响应头。
srcache_store_hide_header
语法:srcache_store_hide_header <header>
默认值:no
配置段:http, server, location, location if
默认情况下,除了以下头缓存所有响应头:
- Connection
- Keep-Alive
- Proxy-Authenticate
- Proxy-Authorization
- TE
- Trailers
- Transfer-Encoding
- Upgrade
- Set-Cookie
可以隐藏多个响应头,不区分大小写。如srcache_store_hide_header X-Foo;
srcache_store_hide_header Last-Modified; srcache_store_pass_header语法:srcache_store_pass_header <header>
默认值:no
配置段:http, server, location, location if
默认情况下,除了以下头缓存所有响应头:
- Connection
- Keep-Alive
- Proxy-Authenticate
- Proxy-Authorization
- TE
- Trailers
- Transfer-Encoding
- Upgrade
- Set-Cookie
可以缓存多个响应头,不区分大小写。如srcache_store_pass_header Set-Cookie;
srcache_store_pass_header Proxy-Autenticate; srcache_methods
语法:srcache_methods <method>...
默认值:srcache_methods GET HEAD
配置段:http, server, location
srcache_ignore_content_encoding
语法:srcache_ignore_content_encoding on|off
默认值: srcache_ignore_content_encoding off
配置段:http, server, location, location if
内容是否编码。
建议后端服务器禁用gzip/deflate压缩。在nginx.conf配置:proxy_set_header Accept-Encoding ""; srcache_request_cache_control
语法:srcache_request_cache_control on|off
默认值:srcache_request_cache_control off
配置段:http, server, location
当该指令为on时,请求头Cache-Control和Pragma按照下面的方法处理:
1. srcache_fetch查询缓存操作时,当请求头Cache-Control: no-cache 、 Pragma: no-cache 将跳过。
2. srcache_store存入缓存操作时,当请求头Cache-Control: no-store将跳过。
当该指令为off时,将禁用此功能,对于繁忙的站点依赖缓存加速被认为是最安全的。
srcache_response_cache_control
语法:srcache_response_cache_control on|off
默认值:srcache_response_cache_control on
配置段:http, server, location
当该指令为on时,响应头Cache-Control和Expires按照下面的方法处理:Cache-Control: private skips srcache_store,
Cache-Control: no-store skips srcache_store,
Cache-Control: no-cache skips srcache_store,
Cache-Control: max-age=0 skips srcache_store,
Expires: <date-no-more-recently-than-now> skips srcache_store. 该指令优先级比srcache_store_no_store,srcache_store_no_cache,srcache_store_private高。
srcache_store_no_store
语法:srcache_store_no_store on|off
默认值:srcache_store_no_store off
配置段:http, server, location
开启该指令,将强制响应头Cache-Control: no-store。默认为关闭。
srcache_store_no_cache
语法:srcache_store_no_cache on|off
默认值:srcache_store_no_cache off
配置段:http, server, location
开启该指令,将强制响应头Cache-Control: no-cache。默认为关闭。
srcache_store_private
语法:srcache_store_private on|off
默认值:srcache_store_private off
配置段:http, server, location
开启该指令,将强制响应头Cache-Control: private。默认为关闭。
srcache_default_expire
语法:srcache_default_expire <time>
默认值:srcache_default_expire 60s
配置段:http, server, location, location if
控制默认过期时间。当响应头既没有Cache-Control: max-age=N也没有指定Expires时,允许的$srcache_expire变量值。
该值必须小于597hours。
srcache_max_expire
语法:srcache_max_expire <time>
默认值:srcache_max_expire 0
配置段:http, server, location, location if
控制最大缓存时间,此设置优先级高于其他计算方法。
该值必须小于597hours。
默认为0,不限制。
