a code is better than an explanation :

in my **servlet** :

```
...
this.getServletContext
   .getRequestDispatcher("..../foo.jsp")
        .forward(request, response); // (1)

// (2)

this.getServletContext
   .getRequestDispatcher("..../bar.jsp")
        .forward(request, response); // (3)
...

```

if i call the url related to this servlet, I get the following error :

*"Cannot forward after response has been committed"*

because (1) set the jsp to use, (3) try to set another jsp.
(notice : I know it is bad example but this is to provide a minimal code).

What I want is to "stop" the servlet to process any further instructions after (1) :

* (1) is set
* (2) writing something to say I want (1) to be used
* (3) not to be read

How can I do that ?
