# Page.setRequestInterception() method
**Signature:**
```typescript
class Page {setRequestInterception(value: boolean): Promise<void>;}
```
## Parameters
| Parameter | Type | Description |
| --- | --- | --- |
| value | boolean | Whether to enable request interception. |
**Returns:**
Promise&lt;void&gt;
## Remarks
Activating request interception enables [HTTPRequest.abort()](./puppeteer.httprequest.abort.md), [HTTPRequest.continue()](./puppeteer.httprequest.continue.md) and [HTTPRequest.respond()](./puppeteer.httprequest.respond.md) methods. This provides the capability to modify network requests that are made by a page.
Once request interception is enabled, every request will stall unless it's continued, responded or aborted; or completed using the browser cache.
## Example
An example of a naïve request interceptor that aborts all image requests:
```ts
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.setRequestInterception(true);
page.on('request', interceptedRequest => {
if (interceptedRequest.url().endsWith('.png') ||
interceptedRequest.url().endsWith('.jpg'))
interceptedRequest.abort();
else
interceptedRequest.continue();
});
await page.goto('https://example.com');
await browser.close();
})();
```
NOTE: Enabling request interception disables page caching.
