Hello-
I am new to nginx, so this may be a silly question. I set up gzip with the recommended 'gzip_disable "MSIE [1-6]\."' parameter. But this results in long delays and/or "IE cannot download" errors when used with keepalive and other gzip options. It only seems to affect js files, and if I rename the files to .txt extensions they have no problems. Does this mean that gzip doesn't need to be disabled for IE6 any more? Or am I doing something wrong somewhere else in my configuration?

Here is a description of the behavior and a debug log.
When trying to download the static .js file for my site, it takes 30 seconds to complete in IE6, compared to almost instant in chrome/firefox. This 30 second duration depends on the keepalive_timeout setting, which I have at 35. If I change that to 75, the download take 70 seconds to complete. If I change it to 0, the download completes right away. This affects files with the .js extension, but other files don't have this problem (.txt, .html). The debug log for 2 download attempts using IE6 (no service packs applied), first for the file with extension .txt and then for a file with extension .js:

here is my nginx.conf with some comments inline:
[code]
# disable user and pid here. using runit's chpst command instead
#user nginx;
#pid /var/run/nginx.pid;
daemon off;

worker_processes 1;
events {
worker_connections 1024;
}

error_log /var/log/nginx/debug.log debug;

http {
include /opt/nginx/conf/mime.types;
default_type application/octet-stream;

sendfile on;
tcp_nopush on;

keepalive_timeout 35;

gzip on; # if on, IE6 can't download the js file
gzip_disable "MSIE [1-6]\.";
#gzip_disable "MSIE [1-6].(?!.*SV1)"; # same problem with this version
#gzip_vary on; # this causes IE to fail entirely (not a delay)
gzip_http_version 1.1;
gzip_comp_level 2;
gzip_buffers 16 8k; # necessary to work with gzip files larger than 32k
#gzip_static on; # requires ./configure ... --with-http_gzip_static_module

gzip_types text/plain text/css
application/x-javascript text/xml

include /etc/nginx/sites-available/*;

}
[/code]
In the sites-available directory, this is the only file:
[code]
# Configuration file for nginx web server

#gzip_min_length 500;
#gzip_proxied any; # compress info from nodejs server

upstream nodejs_server {
server 127.0.0.1:8124;
}

server {
listen 8090; # for testing. can disable this line to listen on 80
server_name localhost; # for testing, we use the IP address
access_log /var/log/nginx/access.log;

root /home/dbro/public;
index index.html;
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;

# serve static files, and fallback to index.html
location / {
try_files $uri $uri/ index.html;
#expires 1d; # TODO: increase this cache timeout
}

# requests handled by node.js
location = /a {
proxy_pass http://nodejs_server;
}
location = /e {
proxy_pass http://nodejs_server;
}

}
[/code]

Thanks very much for help.
