No idea as it is not documented in the English docs and I can't read Russian.

Assuming it works like the proxy version though (and the English documentation for that is really unclear as it seems to suggest to just use the 'cache_bypass' version and forget about the 'no_cache' version), then my understanding is:

1. ?_no_cache = get from backend but cache response
2. ?_cache_bypass = do not cache response

So if you want to bypass the cache and also not cache that response, then you should be using the two together.

Note though that as said, the English documentation does not state this but again I think I have read Igor posting this somewhere.
