Class FilenameWithVersionResourceCachingStrategy

  • All Implemented Interfaces:

    public class FilenameWithVersionResourceCachingStrategy
    extends Object
    implements IResourceCachingStrategy
    resource caching strategy that adds a version for the requested resource to the filename.

    versioned_filename := [basename][version-prefix][version](.extension)

    the version must not contain the version-prefix so please use an unambiguous value for the version-prefix. The default version-prefix is "-ver-".

    Since browsers and proxies use the versioned filename of the resource as a cache key a change to the version will also change the filename and cause a reliable cache miss. This enables us to set the caching duration of the resource to a maximum and get best network performance.
