nginx proxy_cache_methods doesn't work

[nguyennhatkhang92]

Hi,
I'm try use nginx proxy_cache for caching large file. The following is my idea:

Browser --> Nginx --> Storage

• Nginx is a function of caching and proxy server.
• Storage is contain files server.
• I'm have used ngx.var.upstream_cache_status to determine the status of the HIT file caching but it does'n work, nil value. Then I found this: subrequest proxy cache #125 . I would caching file with only GET method and use HEAD method is checked file caching done(HIT) but proxy_cache_methods doesn't work, proxy_method also. I'm try request from Browser with HEAD, GET method then nginx proxy pass to Storage server with GET methods, I do not understand what the reason.

@nguyennhatkhang92 Because you didn't provide any code nor configuration, I can only guess here. Maybe you read the $upstream_cache_status variable too early or in a wrong context? For example, one should never read this variable in any phase before the header filter phase. In addition, one will not read any valid value in a parent request while the upstream thing is actually in the subrequest.

BTW, I don't understand your HEAD/GET method description.
