Description

Hello there,

I found behavior that looks like bug. I have schema that described on this image (https://sctn.io/wjvs2AkbGO.png):
https://sctn.io/wjvs2AkbGO.png

I expect that nginx should cache both steps, response from APP (with X-Accel-Redirect), and response from IMG with static content (or direcly static content), but it's wont work, it cache only response from IMG.

I din't found any menthions in doc's that nginx won't cache X-Accel-Redirect response.

server {
    listen 80;

    set $skip_cache 0;

    location / {
        proxy_cache app;
        proxy_cache_bypass $skip_cache;
        proxy_no_cache $skip_cache;
        proxy_cache_valid 10m;

        proxy_pass http://app;
    }

    location /internal/ {
        internal;
        proxy_cache images;
        proxy_cache_bypass $skip_cache;
        proxy_no_cache $skip_cache;
        proxy_cache_valid 10m;

        proxy_pass http://img;
    }
}
