All,

I have an nginx config that looks like this…

user www-data;  
worker\_processes 4;  
pid /var/run/nginx.pid;

events {  
worker\_connections 768;

# multi\_accept on;

}

http {  
sendfile on;  
tcp\_nopush on;  
tcp\_nodelay on;  
keepalive\_timeout 65;  
types\_hash\_max\_size 2048;

include /etc/nginx/mime.types;  
default\_type application/octet-stream;

access\_log /var/log/nginx/access.log;  
error\_log /var/log/nginx/error.log;

gzip on;  
gzip\_disable “msie6”;

include /etc/nginx/conf.d/_.conf;  
include /etc/nginx/sites-enabled/_;  
}

In the included sites-enabled/portal file, there is a server section  
that has:

server {  
listen 80;  
server\_name [portal.xxx.com](http://portal.xxx.com);  
rewrite ^ https://portal.xxx.com$request\_uri? permanent;  
proxy\_no\_cache 1;  
proxy\_cache\_bypass 1;  
}

Note that both proxy\_no\_cache and proxy\_cache\_bypass are set to 1.  
However, it appears that caching _is_ occurring.

Why? How do we disable this?

Thanks,  
Doug.

What? What exactly do you want to disable?

The proxy\_\* directives are related to the proxy module, and they only  
have  
meaning in combination with proxy\_pass.
