Directio and proxy_cache

Server NGINX
1

Hello,

Is it possible to have proxy_cache use directio? Will it listen to the
directive?

I want nginx to serve the content from the cache directly, without going
through the linux page cache.

Have a great vacation Igor!

Thanks,

John

No, currently proxy_cache does not allow directio. I can say right now
the reason why, but you may try to control it by changing in
src/http/ngx_http_file_cache.c

of.min_uses = clcf->open_file_cache_min_uses;
of.events = clcf->open_file_cache_events;
  • of.directio = NGX_OPEN_FILE_DIRECTIO_OFF;

  • of.directio = clcf->directio;

    if (ngx_open_cached_file(clcf->open_file_cache, &c->file.name, &of,
    r->pool)
