## IGridJsJsonCache.GetCacheKey method

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).

```csharp
public string GetCacheKey(string uid, string fileName)
```

| Parameter | Type | Description |
| --- | --- | --- |
| uid | String | Unique identifier of the file (may differ per load) |
| fileName | String | Original file name |

### Return Value

Cache key
