WebPageTest

thompsonpaul · 02-24-2018, 05:12 AM

I run a test which gives an F for browser caching and a long list of items with no expiry header.

But the waterfall clearly shows that on second load those files aren't' being redownloaded, and I know expiry headers are being applied in htaccess.

This happens on a number of sites - here's an example
https://www.webpagetest.org/result/18022...view_step1

Any idea what's up with this?

Because you're not caching them properly. Gtmetrix returns the same.

And yet I'm using the exact htaccess caching code provided by GTMetrix themselves. And the waterfalls from webpagetest clearly shows that the objects ARE cached as they are not redownloading on second page load. Further supported by the fact that the repeat page load is twice as fast as initial page load.

I didn't say that you weren't caching things, I said that you're not doing it properly.

For reference, here's what I use and it checks out fine.

Browsers will use a heuristic to cache resources for a period if not explicitly specified. Your static resources don't have caching headers so the htaccess rules aren't working: https://www.webpagetest.org/result/18022...1_request2

The server is responding as nginx which doesn't use htaccess (that's for Apache).

Oh ok, he's using nginx. I don't know much about it but this article should help.

If not, he should follow these results.
