Hi,
We have a page rule for caching .json files. It was working fine but suddenly stopped working. There was no change in origin response headers. No other page rule matches the pattern.
I have attached screenshot of page rule (note: I have replaced my real domain name)
Here are origin response headers:
< HTTP/1.1 200 OK
< Server: nginx
< Date: Fri, 09 Jul 2021 04:34:46 GMT
< Content-Type: application/json
< Content-Length: 956
< Connection: keep-alive
< Vary: Accept-Encoding
< ETag: "3bc-5c5de3e0cef80"
< Accept-Ranges: bytes
< Referrer-Policy: no-referrer-when-downgrade
< Pragma: public
< Cache-Control: max-age=31536000, public
< X-Powered-By: W3 Total Cache/2.1.5
And here are the response headers in the browser:
cache-control: public, max-age=31536000
cf-apo-via: origin,nohtml
cf-cache-status: MISS
cf-ray: 66bed63e3caa19f5-SIN
