Application context path

Understand the idea

The server can host multiple applications on one port. A request first identifies the application, then the route inside it. Deploying todo-servlet-jsp.war normally uses /todo-servlet-jsp as its context path.

A concrete example

/todo-servlet-jsp/todos/new
 context path     route

In the application

Redirects use getContextPath(); JSP c:url adds the context path to application-relative URLs.

A hard-coded /todos link points at the server root unless you account for the deployment context.
