Is it correct that when $content_length > client_body_buffer_size,
then $request_body == “” ? If so this would be worth documenting at
I am using:
proxy_cache_methods POST; proxy_cache_key "$request_method$request_uri$request_body";
Which works for small requests, but for large requests clients got
very strange results due to $request_body being empty and hence
getting false cache hits for completely different form posts.
Is there something available like $body_hash that can be used as a
caching key even for large request bodies? Or alternatively, how
would I configure nginx to not cache requests when content_length
is larger than client_body_buffer_size?
