Hello.

Thank you for the explanation. I now understand the problem and it is now working.

I want to add a condition where if a cookie with the name sess_id is included in the request, then the cache would be bypassed. I tried the following

if ($http_cookie ~* "sess_id") {
set $no_cache "1";
}

proxy_no_cache $no_cache;
proxy_cache_bypass $no_cache;

but it doesn't seem to work. What is the correct way to do this? Thank you very much.
