Guzzle HTTP GET requests not caching

Website, Application, Performance

Active Subscription: Free Plan

Page Rule:
Maching URL: https://example.com/*

  • Cache Level: Cache Everything
  • Edge Cache TTL: 14 days
  • Browser Cache TTL: a year

I am using two methods to send a GET request to my URLs:

  1. Google Chrome desktop browser
  2. PHP Guzzle HTTP client

HTML response is returned in both cases.

But, HTML response is cached on Cloudflare if I use a desktop browser like Google Chrome and is not cached, when I use Guzzle HTTP Client.

Any clues or ideas on this problem?

Can you capture and share a request with debug = true. Redact your domain name in the response if you need to.

That seems to show a cached response being delivered. Are you seeing something else?

Thank you.

The page itself is cached successfully, but the resources like CSS and JS files are not. Thus page load time is too long

Can you rerun the test on one of the uncached files? Are they served through a hostname which is patched by your page rule? Do they have a CF-Cache-Status response header?

Yes they have:

CF-Cache-Status: 1

too.

Would you please check this more detaild explanation of the problem to this point:

Multiple HTML‌ versions are cached for same URL but different user agents
