 * Phase 2 , deal request parameters before sending to target server 
 * Phase 3 , after getting response from target server, deal it before sending to client
 
+#### **Phase 0**
 * `summary` the summary of this rule file. AnyProxy will show it to user.
-* **Phase 1** `shouldInterceptHttpsReq` whether https request should be intercepted. If `false` is returned, https requests will not be decrpted. This is only available after certificated has been generated and configured.
-* **Phase 1** `shouldUseLocalResponse` whether you want to response this request with local data. If it returns true, `dealLocalResponse` will be called and other function about target server will be ignored.
-* **Phase 1** `dealLocalResponse` if `shouldUseLocalResponse` returns true, this function will be called, and you should use the ``callback`` function to provide statusCode, response header and response data.
-* **Phase 2** `replaceRequestProtocol` before sending request to real server, this function will be called to decide whether a new protocol should be used. For example, returning "http" for a https request means you will send this request with https. The argument `protocol` is the origin protocol of request. Leave it blank if not necessary.
-* **Phase 2** `replaceRequestOption` AnyProxy internally use ``require('http').request(option,[callback])`` to send request, and here is the ``option`` anyproxy will use. Return your own one when needed. Along with `replaceRequestProtocol`, it is rather easy for you to forward the request to any other server. Leave it blank if not necessary. Ref about `option` : [http://nodejs.org/api/http.html#http_http_request_options_callback](http://nodejs.org/api/http.html#http_http_request_options_callback)
-* **Phase 2** `replaceRequestData` get and replace user's request body
-* **Phase 3** `replaceResponseStatusCode` replace the status code of target server, and this status code will be sent to client
-* **Phase 3** `replaceResponseHeader` replace the response header of target server, and this response header will be sent to client
-* **Phase 3** `replaceServerResDataAsync` use `callback` to give your response data
-* **Phase 3** `pauseBeforeSendingResponse` pause time in ms before sending response to client.
