Hi @infrateam,

how to know for how much time cloudflare is caching

I believe you are referring to Edge Cache TTL.

Edge Cache TTL (Time to Live) specifies the maximum time to cache a resource in the Cloudflare global network. Edge Cache TTL is not visible in response headers and the minimum Edge Cache TTL depends on plan type.

like 5 min/2hrs etc via chrome browser?

I believe here you are referring to Browser Cache TTL.

The Browser Cache TTL sets the expiration for resources cached in a visitor’s browser. By default, Cloudflare honors the cache expiration set in your Expires and Cache-Control headers but overrides those headers if:

  • The value of the Expires or Cache-Control header from the origin web server is less than the Browser Cache TTL Cloudflare setting.
  • The origin web server does not send a Cache-Control or an Expires header.

Unless specifically set in a cache rule, Cloudflare does not override or insert Cache-Control headers if you set Browser Cache TTL to Respect Existing Headers.

@malmeida ,Thanks for the input. Actually i have website https://epaper.telegraphindia.com/ i want to check what is caching time on this as it is frequently causing the up/down/slowness which lasted for 2-3 min only but during the same time my origin server is responding properly.

I want to diagnosis issue and also want to implment the caching on this as we made the changes only once in a day which is 8-9 AM IST rest of the day content doesn’t change.

  1. if the content is change is there any mechanism or API which can purge the content/url without login to dashboard and can be given to developer.
  2. Also want to implement the edge caching for this website like 6 or 12 hrs kind of thing.

Kindly help here as i am new here.
