Provides URLs for resources that change whenever their content changes.
To make browsers update their caches of resources immediately when the resource changes, the absolute URLs of resources can now be made to contain a hash of the resource’s contents, so it will look like /++noop++12345/@@/myresource instead of /@@/myresource.
In developer mode the hash is recomputed each time the resource is asked for its URL, while in production mode the hash is computed only once, so remember to restart the server after changing resource files (else browsers will still see the old URL unchanged and use their outdated cached versions of the files).
To use this package, include its configure.zcml and use
five.hashedresource.interfaces.IHashedResourceSkin or a skin that inherits from
