Re: [squid-users] Reverse cache for HLS streaming

I have seen your logs and it seems like you have user CURL to fetch a
simple get while the clients are requesting a partial content of the
video and squid in any version dosn't cache them yet.
You can try other alternatives that can offer you this kind of feature
or reassess the way your application works.
