Create a new cache instance using the given type ID and ID. This is protected as the type_id will typically be set
statically by subclasses.
| type_id |
A string identifying the type of object being cached. This has to be suitable for use as a directory name; i.e. lower case, hyphen- separated. |
| id |
A string identifying the particular cache instance. This will form the file name of the cache file, but will be escaped beforehand, so can be an arbitrary non-empty string. |
