Not that I am aware of, for proxy_cache.

Not that I am aware of.

If you do find a way, and it happens too late to affect proxy_cache,
then you can possibly get around that by doing two proxy_pass'es --
one with caching to another, which strips the Set-Cookie headers that
you don't want to see after proxy_pass'ing to the "real" upstream.

But you may be better off configuring the upstream server not to send
the Set-Cookie header that you don't want.

That would presumably be more reliable, if it is doable.

Good luck with it,
