nginx is not using gzip to talk to backend servers
- by Michael Gorsuch
Our web servers are running IIS 7 and are configured to compress dynamic and static content. When I hit these servers directly, gzip compression works.
I recently placed nginx in front of them, and gzip compression has stopped. I was able to work around this by explicitly enabling gzip compression on nginx itself, but that seems a little inefficient considering I have half a dozen backends and only one active nginx box.
It appears that nginx is stripping out the Accept-Encoding header. Does anyone have any advice for how to 'correct' this behavior?
A sample configuration:
upstream backend {
server 127.0.0.1:8080;
}
server {
listen 80;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
location / {
proxy_pass http://backend;
}
}
