在本章,http请求对象使用httprequst来表示(jdk中并不存在这个类 我们自己写的),它实现了HttpServletRequest接口。 在使用的时候httprequst会被转型成HttpServletRequest,并作为servlet的service方法的参数而调用。 所以我们得设置每个httprequest实例的成员变量供servlet实例使用,需要设定的值包括uri,查询字符串,参数,Cookie...
因为连接器不知道servlet的类型(即它是否实现javax.servlet.Servlet,扩展javax.servlet.GenericServlet或扩展javax.servlet.http.HttpServlet),所以连接器必须始终提供HttpServletRequest和HttpServletResponse的实例。 In this chapter's application, the connector parses HTTP request headers and enables a servlet to obtai...

To create a new session or gain access to an existing session, use the HttpServletRequest method getSession(), as shown in the following example:HttpSession mySession = request.getSession();getSession() returns the valid session object associated with the request, identified in the session cookie...

Tomcat starts up using the standard start up sequence. When the Host object is created, a cluster object is associated with it. When the contexts are parsed, if the distributable element is in place in web.xml Tomcat asks the Cluster class (in this caseSimpleTcpCluster) to create a manager...
1. 创建一个HttpRequest对象。 2. 创建一个HttpResponse对象。 3. 解析HTTP请求的第一行和头部,并放到HttpRequest对象。 4. 解析HttpRequest和HttpResponse对象到一个ServletProcessor或者 StaticResourceProcessor。像第2章里边说的,ServletProcessor调用被请求的servlet的service方 法,而StaticResourceProcessor发送一个静态...
