I added port 80 in my listener.

# HTTPS server

server {  
listen 80;  
listen 443 ssl;

Gzip still works on 443, but css/js are not getting gzipped in port 80.

My nginx.conf has  
gzip on;  
gzip\_vary on;  
gzip\_min\_length 500;  
gzip\_buffers 4 32k;  
gzip\_comp\_level 6;  
# gzip\_proxied expired no-cache no-store private auth;  
gzip\_proxied any;  
gzip\_types text/plain text/css text/xml text/javascript  
application/json application/javascript application/x-javascript  
application/xml application/xml+rss;  
# gzip\_types text/plain text/css application/json  
application/x-javascript text/xml application/xml application/xml+rss  
text/javascript;  
gzip\_disable “MSIE [1-6].”;

I tried adding this but it didn’t seem to help  
# it wasn’t compressing for port 80  
gzip\_http\_version 1.0;

I can also see if I do  
curl --header “Accept-Encoding: gzip,deflate,sdch” -sI

curl --header “Accept-Encoding: gzip,deflate,sdch” -sI

only the https shows  
Content-Encoding: gzip

What am I missing??

Thanks,
