Problem with uwsgi_no_cache

August 13, 2015 12:06AM
Hi all -

I'm attempting to exclude application/json data from storing in nginx's cache. All other content types are OK to cache. I thought that the below config would work for me, but nginx is still caching everything that is proxying. What am I doing wrong?

## in http block ##
map $http_content_type $no_cache {
default 0;
"application/json" 1;

## in vhost block ##
location / {
uwsgi_cache www;
uwsgi_cache_valid 200 10m;
uwsgi_cache_methods GET HEAD;
uwsgi_cache_bypass $no_cache;
uwsgi_no_cache $no_cache;
add_header X-uWSGI-Cache $upstream_cache_status;
include uwsgi_params;
uwsgi_pass www;

I've tried a few other ways to set $no_cache to 1 for json content. Tried the following in both the server block and the location / block.
if ($http_content_type = "application/json") {
set $no_cache 1;

Here's my build:
nginx version: nginx/1.6.2
