**Returns:**
boolean
### getCacheKey(String uid, String fileName) {#getCacheKey-java.lang.String-java.lang.String-}
```
public String getCacheKey(String uid, String fileName)
```


Generate a cache key. Customers can decide whether to include the uid based on business requirements. - If only the file name matters: ignore uid and use fileName only (recommended, allows sharing cache across same file). - If distinguishing files with the same name is required: use uid (strict mode).

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
