To use request.headersArray()
in @playwright/test, you should know that it returns an array of all request HTTP headers, with header names not lower-cased. Headers with multiple entries appear multiple times in the array.
Regarding max-age
, it's an optional parameter in the Cache-Control header of an HTTP response, specifying how long a cached resource remains fresh. When a browser receives a response with a max-age value, it caches the resource for that duration before making another request.
For example, consider this Cache-Control header: "Cache-Control: max-age=3600". It means the resource can be cached for up to one hour (3600 seconds) before it's considered stale and needs revalidation through another server request.
Here's a TypeScript example using @playwright/test to intercept a request and log the headers array:
import { test, expect } from '@playwright/test';
test('Log request headers array', async ({ page }) => {
// Intercept requests
await page.route('**/*', (route, request) => {
// Log the headers array
console.log(request.headersArray());
// Continue the request
route.continue();
});
// Navigate to the website
await page.goto('https://ray.run/');
});
In summary, request.headersArray()
retrieves all headers associated with an HTTP request, while max-age
is used in caching mechanisms to define how long resources should stay fresh before revalidation.
