What are the correspondent of Servlet and Applet in .NET?

问题 I am trying to understand what's the correspondent of servlets and applets in .NET but I don't have much experience in JAVA. I am thinking applets could be compared to the silverlight stuff, meaning you code independently from the browser, but then it's not like that since (between other things) you can re-use an applet outside the browser. I need to demonstrate web technologies for a JAVA-based college-course and I can use .NET as long as I can demonstrate the same stuff . Any help or ideas

问题 I get confused between the two ApplicationContext and ServletContext when it comes to Spring MVC Application. I know that There is just only One ApplicationContext per Spring Web Application and there is also just only One ServletContext per web application.

Is there any way we can get only this part /secure/users , i.e. the URI without context path? 回答1: If you're inside a front contoller servlet which is mapped on a prefix pattern, then you can just
