Class TkFlash

java.lang.Object

org.takes.facets.flash.TkFlash

All Implemented Interfaces:

Take

public final class TkFlash
extends Object
implements Take

Take that understands Flash cookie and converts it into a HTTP header.

This decorator helps your "take" to automate flash messages and destroy cookies on their way back, from the browser to the server. This is what a browser will send back:

 GET / HTTP/1.1
 Host: www.example.com
 Cookie: RsFlash=can%27t%20save%20your%20post%2C%20sorry/SEVERE

This decorator adds "Set-Cookie" with an empty value to the response. That's all it's doing. All you need to do is to decorate your existing "take", for example:

 new FtBasic(
   new TkFlash(TkFork(new FkRegex("/", "hello, world!"))), 8080
  ).start(Exit.NEVER);
 }

The class is immutable and thread-safe.
