+# DESIGN
+
+在此重大更新之前, 下载器 & 选择器 & 数据管理是耦合在一起的, 经过许久思考我决定把它们解耦出来, 这样用户可以自由的选择他们喜爱的组件. 比如说, 下载器使用框架自带的Downloader、WebClientApi、苏菲的HttpHelper等; 解析器可以使用框架自带的Extraction、AngleSharp等;
+
+###  Dowloader
+
+Downloader is a independent module to help user to download data from target website. There are a lot of details, see below:
+
+1. Two ways to set cookie, one is call the AddCookie method in downloader, it add cookie to CookieContainer so impact every request.
+Set cookie header in request, the result is combine you cookie header and cookies in CookieContainer. 
+2. CookieInjector in downloader is invoked one time, and inject cookies to CookieContainer.
+
+### Scheduler
+
+#### Request hash
+
+1. Same url different headers are different requests, so headers are a factor  
+2. There is a CycleRetryTimes property in a request, if value are different, then requests are different. Depth property is not
+a factor.
