# init(memoryCapacity:diskCapacity:diskPath:)

Creates a URL cache object with the specified values.

```
init(memoryCapacity: Int, diskCapacity: Int, diskPath path: String?)
```

## Parameters

`memoryCapacity`

The memory capacity of the cache, in bytes.

`diskCapacity`

The disk capacity of the cache, in bytes.

`path`

In macOS, `path` is the location at which to store the on-disk cache.

    In iOS,     `path`     is the name of a subdirectory of the application’s default cache directory in which to store the on-disk cache (the subdirectory is created if it does not exist).

## Return Value

The initialized cache object.

## Discussion

The returned cache instance is backed by disk, so you have more leeway when choosing the capacity for this kind of cache. A disk cache measured in the tens of megabytes should be acceptable in most cases.

## See Also

[`shared`](/documentation/Foundation/URLCache/shared)

The shared URL cache instance.
