Pictures not served by CDN77

can you be sure that cdn777 supports the .webp image extension please?

Hi Emre

I got the following response from CDN77:

Hello,

Yes, we support caching .webp images.

Also for the two no-caching images I tried to curl them-

curl -I “https://mirkoreichlin.ch/wp-content/uploads/apollo13_images/DSC01215-6n22e74t0e25h6whob2xrhm2y3zkj55hsg.jpg”
HTTP/1.1 200 OK

Server: Apache/2.4
Upgrade: h2,h2c

Last-Modified: Mon, 25 Dec 2017 10:24:18 GMT

Cache-Control: max-age=2592000
Expires: max-age=2592000, public
Content-Type: image/jpeg

The problem is with the part “Expires: max-age=2592000, public”
The correct syntax should look – Expires: <http-date>
for example: Expires: Wed, 10 Oct 2018 07:28:00 GMT .
Please change this part to correct one.

Best,

I forwarded this message to the theme provider as well. Or is this a problem from the Cache Plugin?

Thank you, for your help,
Mirko

WPFC creates .webp extension for the images. If the CDN does not work support webp, the images do not work properly.

CDN77 supports .webp as described above. But there seems to be a syntax problem in the description of the “Expires:” attribute. Can you please look in to this?

Kind regards
Mirko

Please take a look at the following image. What’s the problem?

The Problem is:

Instead of

Expires: max-age: 2592000, public

It should say something like:

Expires: Mon, 25 Dec 2017 10:24:18 GMT

At least according to CDN77.

Kind regards
Mirko

hmm. then you should disable “browser caching” on the settings of WP fastest cache.
and you should add the rules which cdn777 sends you into htaccess.
