Hi,

When the caching in the fastcgi parameters are active, site users are directed elsewhere (not to the site). I think there is a conflict with the set $cache_uri directive. Though for some reason when the $cache_uri options are commented out, the site doesn't work at all.

server {
listen *:80;
index index.php index.html index.htm;

server_name www.example.com
set $cache_uri $request_uri;

if ($request_method = POST) {
set $cache_uri 'no cache';
}

if ($query_string != "") {
set $cache_uri 'no cache';
}

if ($request_method !~ ^(GET|HEAD|POST)$ ) {
return 444;
}

error_page 404 /404.html;

# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /favicon.ico {
log_not_found off;
access_log off;
}

location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}

}

access_log off;
expires max;
break;
}
if ($uri !~ ^/index\.php) {
rewrite ^/(.*)$ /index.php/$1 last;
}

}
