### Properties

The following table describes properties for the `default-helper` element.

Table A–37 `default-helper` Properties

Property | Default | Description
--- | --- | ---
`cacheKeyGeneratorAttrName` | Uses the built-in `default` cache-helper key generation, which concatenates the servlet path with key-field values, if any. | The caching engine looks in the `ServletContext` for an attribute with a name equal to the value specified for this property to determine whether a customized `CacheKeyGenerator` implementation is used. An application can provide a customized key generator rather than using the `default` helper. See CacheKeyGenerator Interface.
