Hello

RFC2616 14.9.4 Cache Revalidation and Reload Controls
"End-to-end reload"
[...]The server MUST NOT use a cached copy when responding to such a
request[...]

Such a request can be triggered from the browser by holding SHIFT
and using reload button; it's often used by web developers to get
uncached response from the original server. Unfortunately nginx seems
to ignore such request and answers from the cache.

Is it possible to make a quick workaround bypassing the cache for such
requests using some request header variable conditional if?

server {
listen 127.0.0.1:8000;
server_name localhost;

location / {
proxy_pass http://192.168.10.10:80/;
proxy_redirect off;

if ($request_header !~ "Cache-Control: no-cache") {
proxy_cache one;
proxy_cache_valid 200 1h;
}
proxy_pass_header Set-Cookie;

proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

?
