srcache_nginx模块相关参数介绍，可以参见《memc_nginx+srcache_nginx+memcached构建透明的动态页面缓存》。 redis是一种高效的key-value存储。
下面举一例应用，看配置：

测试：
redis实例下：
可以记录下日志来测试加缓存前后的耗时。日志格式如下：
|
1 2 3 |
log_format srcache_log '$remote_addr - $remote_user [$time_local] "$request" ' '"$status" $body_bytes_sent $request_time $bytes_sent $request_length ' '[$upstream_response_time] [$srcache_fetch_status] [$srcache_store_status] [$srcache_expire]'; |

这个是不是还需要一个redis模块？
