The line between web servers and application servers is blurred. Web服务器和应用程序服务器之间的界线模糊。 One common definition is that web servers can be contacted through HTTP and HTTPS only, but application servers can be contacted through other means (messaging services, remote method invocation, etc) in addition to web protocols. 一个常见的定义是，只能通过HTTP和HTTPS与Web服务器联系，但是除了Web协议之外，还可以通过其他方式（消息服务，远程方法调用等）与应用程序服务器联系。 Application servers also provide a container that takes care of certain software requirements (such as transactions and resource management) for you automatically. 应用程序服务器还提供了一个容器，可以自动为您处理某些软件要求（例如事务和资源管理）。

And rich internet application are web apps that act like desktop apps. 富互联网应用程序是类似于桌面应用程序的Web应用程序。 They don't have to reload the page every time you perform an action, and they have a wider variety of input methods. 他们不必每次执行操作都重新加载页面，并且它们具有多种输入法。 This can be done in a variety of ways, including Flash, Silverlight, Java, or regular HTML with Ajax Javascript. 这可以通过多种方式完成，包括Flash，Silverlight，Java或带有Ajax Javascript的常规HTML。
