          org.openqa.selenium.server.FutureFileResource

All Implemented Interfaces:

java.io.Serializable

public class FutureFileResource
extends URLResource

Future File Resource. DGF This is as per the standard Jetty FileResource, but its constructor is private, so I've copied-and-pasted it rather than extending it. It's just like the regular FileResource, but it always claims its lastModified date is in the future, to prevent caching. Handle resources of implied or explicit file type. This class can check for aliasing in the filesystem (eg case insensitivity). By default this is turned on if the platform does not have the "/" path separator, or it can be controlled with the "org.openqa.jetty.util.FileResource.checkAliases" system parameter. If alias checking is turned on, then aliased resources are treated as if they do not exist, nor can they be created.
