How to know when Redis cache is working?

I took a look at the headers and I see

X-Powered-By:EasyEngine 3.3.14
X-SRCache-Fetch-Status:BYPASS
X-SRCache-Store-Status:BYPASS

And from that I gather that it bypasses the cache. Does it ? If that’s the case - how do I make it hit the cache ?

No hhvm, no page speed. Only Redis is enabled.

I always take:

X-SRCache-Fetch-Status:MISS
X-SRCache-Store-Status:BYPASS
