Abstract
As time went by, and more and more services could remotely use web applications, the web applications became more complex—and designing and implementing them became a cumbersome process. Most applications imply creating objects and passing them through several states, or creating objects depending on each other. Spring Web Flow (SWF) is a component of the Spring Framework’s web stack that was created to help develop complex applications by reducing the difficulty in development.

Notes
- 1.
The official site of the project ( http://projects.spring.io/spring-webflow/ ) is usually updated late, so it might show an earlier version; the most recent release can be found on the Maven public repositpry site at http://mvnrepository.com .
- 2.
The code for the class is publicly available on GitHub at https://github.com/spring-projects/spring-webflow/blob/master/spring-webflow/src/main/java/org/springframework/webflow/mvc/servlet/FlowController.java .

The GOTO statement (see https://en.wikipedia.org/wiki/Goto ).

1. False. This variable is defined in the first requestScope and a state has two requests. Rendering the view is done in the second request. 2. True. As explained earlier. 3. True. var1 and var4 are defined in flashScope; var3 and var5 are defined in the scope of the rendering requestScope. 4. True. var1 is lost because it is defined when entering the state, and if the page is reloaded, entering the page is done only once. So when the page is reloaded, the flash scope is cleaned and var1 is lost.
