CookieTool Viewtool
The Cookietool Velocity Viewtool allows you to create and access cookies. This class is only designed for use as a request-scope tool. It exposes the methods of the standard CookieTool viewtool.
Note: This viewtool cannot be used directly from a static page — e.g., one served via CDN — but can still be utilized through the Scripting API in such a case.
The following snippet shows how the CookieTool Viewtool is mapped in the toolbox.xml file:
<tool> <key>cookietool</key> <scope>request</scope> <class>org.apache.velocity.tools.view.tools.CookieTool</class> </tool>

$cookietool.foo.value | Returns the Value of the specified cookie |
$cookietool.foo.name | Returns the Name of the specified cookie ("foo", in this case) |
$cookietool.add("bar", "woogie"[, 60]) | Adds a cookie with Name bar, Value woogie, and (optional) MaxAge of 60 seconds |
$cookietool.delete("bar") | Sets the MaxAge of cookie bar to 0, causing its deletion |
