the affiliate module flow is as below:
1. client will register as a affiliate member and we will provide them a banner with unique affiliate id.
2. this client will put the banner at their own side, i.e. put at their blog.
3. For eg , customer A click on that banner, it will redirect to our website.
4, 那我要用什么方法做这些呢? 是用cookies的吗?
