# Disabling HTTP Keep-Alive
|
|
|
|
Next.js automatically polyfills [node-fetch](/docs/basic-features/supported-browsers-features#polyfills) and enables [HTTP Keep-Alive](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Keep-Alive) by default. You may want to disable HTTP Keep-Alive for certain `fetch()` calls or globally.
|
|
|
|
For a single `fetch()` call, you can add the agent option:
|
|
|
|
```js
|
|
import { Agent } from 'https'
|
|
|
|
const url = 'https://example.com'
|
|
const agent = new Agent({ keepAlive: false })
|
|
fetch(url, { agent })
|
|
```
|
|
|
|
To override all `fetch()` calls globally, you can use `next.config.js`:
|
|
|
|
```js
|
|
module.exports = {
|
|
httpAgentOptions: {
|
|
keepAlive: false,
|
|
},
|
|
}
|
|
```
