Hi,

I am attempting to set up nginx for load balancing. HTTP works fine, but I'm intermittently getting corrupted output back from HTTPS. The responses contain garbage after the actual end of the document. There appears to be some randomness/timing to this; the amount of garbage as well as its contents varies. In addition to Web browsers I can replicate this with "openssl s_client" using a single HTTP 1.0 request, no keep-alive or anything.

The load balancing machine is running nginx 0.5.14 on OpenBSD. The balanced servers are Apache 2.2.3 and 2.0.54 on Linux.

Here is a minimal nginx.conf which demonstrates the problem:

worker_processes 1; error_log /var/log/nginx-error.log;

events { worker_connections 1024; }

http { upstream acm-ssl { server 172.22.32.80:443; }

server { listen 443; server_name www-s.acm.uiuc.edu; ssl on; ssl_certificate /etc/nginx/www-s.acm.uiuc.edu.crt; ssl_certificate_key /etc/nginx/www-s.acm.uiuc.edu.key; keepalive_timeout 70;

location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass https://acm-ssl; } } }

(And yes, I realize encrypting twice is wasteful; unfortunately we don't yet have the ability to secure the network connection so we need to do it this way.)
