I'm setting up NGINX as reverse caching proxy for my IIS website.
I'm experiencing an issue with the caching of .png and.ashx files. Every time I check the response headers I see: x-cache-status: MISS
The other files are cached as expected.
NGINX is configured as caching reverse proxy with the following arguments:
| Code: | location / {
proxy_pass https://IIS:443;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
location ~* \.(html|css|jpg|png|gif|ico|js|axd|ashx)$ {
proxy_cache cache;
proxy_cache_key $host$uri$is_args$args;
proxy_cache_valid 200 301 302 3h;
expires 3h;
proxy_pass https://IIS:443;
add_header X-Cache-Status $upstream_cache_status;
proxy_cache_revalidate on;
proxy_cache_min_uses 1;
proxy_cache_use_stale error timeout http_500 http_502 http_503 http_504;
proxy_cache_lock on;
}
}
}
|
I have no idea why the .png and .ashx files are not being cached. Any help is appreciated. |

You should post @ https://forum.nginx.org/ the windows mailing list.
But from what i see this should fix your issue.
| Code: |
location ~* \.(html|css|jpg|png|gif|ico|js|axd|ashx)$ {
proxy_cache cache;
proxy_cache_key $host$uri$is_args$args;
proxy_cache_valid 200 301 302 3h;
expires 3h;
proxy_pass https://IIS:443;
add_header X-Cache-Status $upstream_cache_status;
proxy_cache_revalidate on;
proxy_cache_min_uses 1;
proxy_cache_use_stale error timeout http_500 http_502 http_503 http_504;
proxy_cache_lock on;
}
location / {
proxy_pass https://IIS:443;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}

Make that your location setup and ordering.
If that does not work just post here one of the dev's or regular nginx guru's will help. https://forum.nginx.org/list.php?2 |

Actually I set this up with Apache and found that the Cache-Control header was the issue.
I'm not planning on using Nginx because I have to recompile it to enable mod_pagespeed.
Instead I've opted for Apache, since I'm already familiar with it and can easily install the mod_pagespeed plugin. |
