Custom vary and QC CDN
-
Hi, just wanted to check if QC CDN is now supporting custom varies set in Litespeed cache or if I still have to disable the CDN level caching for custom varies to work?
-
For testing purposes I have deactivated the cache on QC, but now Litespeed cache seems to be not caching anything (opened the page in a private browser tab, loaded it several times but Litespeed is showing bkd as cache status, which I think means a “miss”).
Here all the response headers:

x-qc-pop EU-GB-LCY-HYBRID-61I’m wondering why everything seems to be set to “no cache” (cache-control no-store, no-cache, must-revalidate, pragma no-cache). In the Litespeed settings I don’t have any exclusions for caching. I have set certain cache varies, which are also showing in the Litespeed debug log, but seem not to be having any influence on the cache behaviour.
Is there a way to work out what stops the caching to happen?
Hi, I have now re-activated the QC cache, here the report ID: TPZXOCKK
What I want to confirm is:
– does my cache vary against the cookie “onetwo3d_cache_cluster” work? Is there a way to validate this?
– does the cache vary also works with QC caching being active?
