root和alisa的区别
root可以把后面的url完整的映射进文件路径中, 而alias只会将location后的url映射到文件路径
将会生成3个变量:
- request_filename 访问文件的完整路径
- document_root 根据root/alias生成的文件夹路径
- realpath_root 将document_root中的软连接换车真实路径

当url以 / 结尾时候, 尝试以html/xml/json/jsonp等格式返回root/alias指向的目录的目录结构
concat模块
ngx_http_concat_module模块的功能是当页面需要访问多个小文件时候 , 把他们的内容合并到一次http响应中返回 , 提升性能 , 他的地址是Tengine(https://github.com/alibaba/nginx-http-concat)
如何使用:
在url后面跟上?? , 后通过多个, 逗号分隔文件 , 如果有参数 ,则在最后添加?添加
比如:https://g.alicdn.com/??kissy/k/6.2.4/seed-min.js,kg/global-util/1.0.7/
