public class RotatingVirtualURIMapping
extends RegexpVirtualURIMapping

An extension of RegexpVirtualURIMapping that allows a rotation between different destination urls. In order to rotate toURI must contain the * that will be replaced by a random number between start (default is 1) and end (defaults is 3).

An additional property padding can specify the left 0 padding for numbers (defaults is 2). So for example a destination url like forward:/banner/image_*.jpg will randomly forward the request to /banner/image_01.jpg, /banner/image_02.jpg or /banner/image_03.jpg

mapURI

public VirtualURIMapping.MappingResult mapURI(String uri)
Maps an incoming URI to a new target URI. Returns a VirtualURIMapping.MappingResult describing the new URI and the level of match. The new URI can be prefixed with "redirect:", "permanent:" or "forward:" to trigger either a temporary redirect, a permanent redirect or a forward respectively. For redirects the URI can be absolute or relative within the web application (the context path is added automatically). If the mapping does not apply to the input URI this method returns null.

Parameters:
uri - the URI of the current request, decoded and without the context path
Returns:
a VirtualURIMapping.MappingResult with the target URI and level or null if the mapping doesn't apply
