本文详细介绍了EmWebServer处理HTTP请求的过程，从初始化请求到发送响应的每一个步骤，包括网络处理、认证支持、URL钩子配置等内容。

在收到了HTTP request后，调用次序如下：

ewsNetHTTPStart() //initialize the request

//Server会创建一个request context对象，来描述request的所有信息，以及内部关于处理request的状态的信息，eg EwsContext ewsContext;

ewsContextNetHandle() //retrieve the network handle during request processing

ewsNetHTTPReceive() //transfer the data to the EmWeb Server

ewsRun() //start the request processing

ewaURLHook() //If you have configured the server for URL hook support, it will pass control to your application.

ewaAuth...() //If you have configured the server for authentication, the server will validate the user credentials before it will grant access to the requested resource

ewsNetHTTPCleanup() //If access is not authorized, the server sends a 401 Unauthorized HTTP response an calls the

ewsContext...() //deal with the request

ewaNetHTTPSend() //to send the content to brower

ewsNetHTTPCleanup()
