hi, I have sevral questions about source code. 1.about the directive proxy_cache_valid 200 5m, how does nginx get cache valid time by its status? it seems function ngx_http_file_cache_valid() in file ngx_http_file_cache.c isnt used. I've checked other functions, but nothing found. 2.now, I need to set cache valid time by extensions, not status. there are parameters status_n, status_line in u-&by demi - Nginx Mailing List - English
