Send me settings of /etc/nginx/nginx.conf and then /etc/sites-available/app.

The format of the file is not opening up on my system as I am on windows right now.

Also if you have some logs that would be great.

Hi Hashmi,

thank you for your suggestion.

I tried to set proxy_pass for the location I don't want to cache, but I don't see caching working properly on my browser.

Could you give a look?
I will attach a mockup of settings,may you want to comment or edit it there so that is more readable to me and also other people?

I want to cache all /api location, except /api/search

In attachment what I tried (I removed from settings things not relevant to this).

thank you,

Luigi

Create a separate block to exclude certain endpoint above others. 

You can also try following approach.

Hello,

I want to cache all api endpoints except of one: /api/search endpoint.

Do I need to specify settings for each of the endpoints?

My configuration use nginx as server on port 8000 and port 80 as virtual proxy server.

Please not I removed settings not related to question to minify the post!

server {

listen 8000 default_server;

# Set Cache for my Json api

                # I want to cache everything but /api/search endpoint

location ~* \.(?:json)$ {

 expires 1M;

 access_log off;

 add_header Cache-Control "public";

}

           

location /api {

include uwsgi_params;

uwsgi_pass unix:/var/www/awesome3-gamma/app.sock;

allow [MY DNS];

deny all;

}

}

# Set cache dir

proxy_cache_path /tmp/nginx levels=1:2 keys_zone=my_zone:10m inactive=60m;

proxy_cache_key "$scheme$request_method$host$request_uri";

# Virtualhost/server configuration

server {

listen   80  default_server;

# here I cache /api
        # how to avoid caching /api/search ?
        

location /api {

add_header X-Proxy-Cache $upstream_cache_status;

proxy_cache my_zone;

proxy_cache_use_stale updating;

proxy_cache_lock on;

        proxy_cache_valid 30d;

proxy_ignore_headers X-Accel-Expires Expires Cache-Control;

          proxy_pass [my site route api]

}

}


I am looking at:

http://stackoverflow.com/questions/29466494/nginx-turn-off-cache-for-a-specific-file

http://stackoverflow.com/questions/29466494/nginx-turn-off-cache-for-a-specific-file

tried with following block on server listening on port 8000

location /api/search {      expires off;  }

but got error 500.

Must it go before /api location, afterwards, or it does not matter the order?

Any idea of what I am missing ?

I would like to avoid specify same settings for all API endpoints
