Overview of this book

The Play framework is the new kid on the block of Java frameworks. By breaking with existing standards the play framework tries not to abstract away from HTTP as most web frameworks do, but tightly integrates with it. This means quite a shift for Java programmers. Understanding these concepts behind the play framework and its impact on web development with Java are crucial for fast development of applications. The Play Framework Cookbook starts where the beginner documentation ends. It shows you how to utilize advanced features of the Play framework – piece by piece and completely outlined with working applications! The reader will be taken through all layers of the Play Framework and provided with in-depth knowledge from as many examples and applications as possible. Leveraging the most from the Play framework means to think simple again in a java environment. Implement your own renderers, integrate tightly with HTTP, use existing code, improve site performance with caching and integrate with other web services and interfaces. Learn about non-functional issues like modularity or integration into production and testing environments. In order to provide the best learning experience during reading Play Framework Cookbook, almost every example is provided with source code, so you can start immediately to integrate recipes into your own play applications.

Setting up the Lighttpd web server with Play

Lighttpd (pronounced lighty) is another lightweight web server, similar to Nginx, as it also handles requests asynchronously. It is a matter of taste, and which web server you prefer, so this recipe is here for the sake of completeness.

The source code of the example application is available at examples/chapter7/ssl/example-app as well as for examples/chapter7/ssl/example-app-2 for the second application instance. The configuration files for the web server are put in examples/chapter7/lighttpd.

Getting ready

You should have a lighttpd installed on your system and have the the accesslog, proxy, and ssl modules enabled. When using a Debian derived operating system, you can use the lighttpd-enable-mod command, for example: lighttpd-enable-mod ssl.

How to do it...

Simple redirection works like this—put it into /etc/lighttpd/conf-enabled/10-proxy.conf:

$HTTP["host"] == "www.test.local" {
        proxy.server  = ( "" => ((
                 "host" =&gt...
