There are two modules used:
https://github.com/yaoweibin/ngx_http_substitutions_filter_module
https://github.com/aperezdc/ngx-fancyindex
The first one is used for the ``css toggle without cookies'' hack and the second is just to make nice directory listings.
I think some variables were missing in the post where I explained the css switching, so here's the part that takes care of adding the query strings to all links:
server {
if ( $query_string = "" )
{
set $bypass "1";
}
#replace css and add query string to all internal links
subs_filter_bypass $bypass;
subs_filter '<LINK href="/static/styles/(.*?).css"' '<LINK href="/static/styles/$arg_css.css"' or;
subs_filter '<A href="((?!http).*?)(#.*?)?"' '<A href="$1$is_args$args$2"' gr;
subs_filter '<FORM action="(.*?post)"' '<FORM action="$1$is_args$args"' gr;
}I call it a hack because in a perfect world, elements of your app should be loosely coupled and SchemeBBS would handle this, not Nginx. But sometimes you have to chose the way of the ninja especially for nice but non vital features.
cont. (I hit the post length limit. I got a new server today with decent specs so the site will be migrated and the post limit raised)

You'll also probably want to serve static files directly with nginx, even if SchemeBBS can serve them too. And you probably want to cache requests. So, here's a fairly complete nginx.conf:
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
proxy_cache_path /var/cache/nginx levels=1:2
keys_zone=cache:10m inactive=600s max_size=100m;
#limit post requests
map $request_method $limit {
default "";
POST $binary_remote_addr;
}
# Creates 10mb zone in memory for storing binary ips
limit_req_zone $limit zone=post_limit:10m rate=11r/m;
upstream http_backend {
keepalive 20;
server 127.0.0.1:8080;
}
server {
listen 80;
server_name tld.org www.tld.org;
set $prefix "/path/to/schemebbs"
# site root, a static page
location = / {
rewrite ^ /static/index.html;
}
location = /favicon.ico {
rewrite ^ /static/favicon.ico;
}
# static files
location /static/ {
alias $prefix/static/;
}
# serve s-expressions as static files
location /sexp {
alias $prefix/data/sexp/;
autoindex on;
default_type text/x-scheme;
fancyindex on;
fancyindex_time_format "%F %R";
fancyindex_footer "/static/lisp.html";
}
location / {

default_type text/html;

try_files $uri $uri/index @schemebbs;
}
#replace css and add query string to all internal links
