# Page.setRequestInterception() method
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.
See the [Request interception guide](https://pptr.dev/guides/network-interception) for more details.

## Example
An example of a naïve request interceptor that aborts all image requests:
```ts

import puppeteer from '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();
})();
```
