Hello Community,

Is it possible to assign different proxy\_cache\_valid values for  
different file extensions? So for example .jpg could live in the cache  
for 7 days, but .js files would only live for 6 hours?

I guess you could do this with multiple location directives, just don’t  
know exactly how or if it is supported.

Thanks,

John

```
location ~ \.jpg$ {
    proxy_pass ...;
    proxy_cache ...;
    proxy_cache_valid 200 7d;
}

location ~ \.js$ {
    proxy_pass ...;
    proxy_cache ...;
    proxy_cache_valid 200 6h;
}

```

Thanks Igor,

Just want to confirm that the proxy\_cache zone can be the same, so we  
can set different proxy\_cache\_valid 200 values for keys in the same  
proxy\_cache zone?

Thanks

John

Yes, proxy\_cache zone can be the same.
