#### Software Architecture
Software Architecture Description
Based on openresty's nginx+lua, the performance is very good.

1. Install openresty (omitted)
2. lua configuration, see src/openresty/cdnSign.lua
3. nginx, see src/openresty/cdnAuth.conf

#### demo address

* lua test: http://cdnauth.opendfl.org.cn/lua2
* Signature generation: see: src/test/java/utils/CdnSignChainTest.java
* cdn authentication: http://cdnauth.opendfl.org.cn/cdnAuth?sign=71fa33cbd826e7a8618ec5ee9f95f5c3&t=630e5942&path=/t2.jpg
