caching in CDN
Jonathan Stockley 2025-09-09 23:46:11 UTC in Nimble Streamer
Hi, we are trying to use nimble as an origin for VoD being pulled from 5centscdn.com. We have added http_origin = true to the nimble.conf and restarts and no longer see the nimblesessionid parameter in the chunks but 5centscdn still is not caching. Is there anything else we need to configure?

Hello Jonathan,
Could you please provide more technical information, how do you know CDN is not caching? Also, did you try to ask CDN support to clarify the reason it is not caching?
Thank you.

We are using a pull model with 5centcdn.
We have enabled verbose logging and can see the GET requests coming in from 5centscdn for each HLS segment (n_0_0_0.ts, etc).
If we play via the CDN and then after about 10 seconds play again we do not see the GET requests which means the CDN has cached them. However if we wait for about a minute and play again, we see the CDN sending GET requests for the HLS segments. We have configured the CDN to cache for 30 days butit doesn't appear to be caching for anywhere near that time.
Note that the exact same CDN configuration is working fine with Wowza.
