Hello. I have an WP-mu installation as php-fastcgi and nginx as web server.
Here is the cache-related config:

[code]
http {
fastcgi_cache_path /usr/cache/nginx levels=1:2 keys_zone=php:10m;
server {
# ....
location ~ .php$ {
fastcgi_cache php;
fastcgi_cache_key $host$request_uri;
fastcgi_cache_min_uses 1;
#...
}
}
[/code]
is that something wrong there? nginx creates an empty dirs in cache folders, but no files does. Help me, please.

I'm using nginx-0.7.61 on FreeBSD 7.2-STABLE

Do you have a fastcgi_pass statement in that block?

If you are going to do this you should include some cookie checking conditionals so that users aren't able to see the admin's version of the pages. You might be better off with the WordPress super cache plugin.

[b]Jim[/b], there is fastcgi_pass section in [u]location ~ \.php[/u] area. I'm looking for nginx caching solution, WP Super cache is the last variant - if nginx wouldn't work.

Is fastcgi_cache read Cache-control headers?

I understand that. It's part of the fastcgi module. I believe that you need to have the cache statements in the same block as the fastcgi_pass (I could be wrong, I set this up a little while ago but Igor helped me with the configuration). It's why I asked. Feel free to not take my advice.

Here's a working configuration where I have a 6-8GB cache of image files:

[code]
location ~ (png|gif|jpg|jpeg)$ {
fastcgi_pass unix:/tmp/my.sock;
fastcgi_cache one;
fastcgi_cache_key unix:/tmp/my.sock.1$request_uri;
fastcgi_ignore_headers Cache-Control Expires;
fastcgi_cache_valid 200 302 1d;
fastcgi_cache_valid 301 7d;
fastcgi_cache_valid any 5m;
include /usr/local/nginx/conf/fastcgi_params;
fastcgi_param SCRIPT_NAME myscript;
fastcgi_buffers 64 8k;
}

[/code]
