Hi Maxim,
Thanks for your prompt answer !
That's exactly what I'm using currently, but was thinking if there is
some more elegant/performance-effective way of doing this thing.
Regards

I have the following working scheme:
Client --> Nginx [caching] --> Apache [backend]
Sometime the backend returns headers, which I want to modify before
nginx caching engine decides how to treat them. One such example is when
backend returns Vary: header.
I want to achieve the following:
[Apache backend returns Vary: User-Agent, Header2] --> [Nginx Modifies
"Vary:" and removes User-Agent] --> [Nginx caching sees only 'Vary:
Header2' (without User-Agent)] --> The final result is that Nginx cache
wont take 'User-Agent' into vary considerations. (no cache object per UA).
That's just an example. I would like to do such modification with other
headers also (for example Cache-Control).
Currently I'm already using Nginx Lua integration, but there is no hook
point before the caching engine.
Would be happy for any suggestions about achieving this scenario.
As of now, the only solution would be to use intemediate proxy
(without caching) to modify headers returned by your backend.
