# Class: Pool
Extends: `undici.Dispatcher`
A pool of [Client](Client.md) instances connected to the same upstream target.
Requests are not guaranteed to be dispatched in order of invocation.
## `new Pool(url[, options])`
Arguments:
* **url** `URL | string` - It should only include the **protocol, hostname, and port**.
* **options** `PoolOptions` (optional)
### Parameter: `PoolOptions`
Extends: [`ClientOptions`](Client.md#parameter-clientoptions)
* **factory** `(origin: URL, opts: Object) => Dispatcher` - Default: `(origin, opts) => new Client(origin, opts)`
* **connections** `number | null` (optional) - Default: `null` - The number of `Client` instances to create. When set to `null`, the `Pool` instance will create an unlimited amount of `Client` instances.
* **interceptors** `{ Pool: DispatchInterceptor[] } }` - Default: `{ Pool: [] }` - A list of interceptors that are applied to the dispatch method. Additional logic can be applied (such as, but not limited to: 302 status code handling, authentication, cookies, compression and caching).
