Optimizing resource downloads using a caching proxy – FiveM Cookbook


Server builds starting at pipeline ID 1679 added the ability to configure the fileServer field used for resource downloading using a set of commands:

# Set the file server for the specified resource regex.
# The URL should *not* end with a slash.
fileserver_add ".*" "http://10.10.0.1/files"

# Remove the file server associated with a resource regex.
fileserver_remove ".*"

# List all registered file server patterns.
fileserver_list

# Old command, but **required** to not get corrupted cache entries.
adhesive_cdnKey "someSecurePassphrase"

There’s currently no cache invalidation logic based on hashes (this’ll need yet another server update due to the file server not ignoring query strings + a client update), so make sure to clear your proxy’s cache before you modify/restart a resource.

Here’s an example NGINX configuration for setting this up (but you should, for example, run this behind yet another proxy which offers HTTP/2 over TLS, or otherwise set this up properly – we’re expecting the community to provide fleshed-out examples on the forums):

default.template

proxy_cache_path /srv/cache levels=1:2 keys_zone=assets:48m max_size=10g ;
log_format asset '$remote_addr - [$time_local] "$request" $status $body_bytes_sent $upstream_cache_status';

server {
        listen 80;

        location /files/ {
                access_log /dev/stdout asset;
                add_header X-Cache-Status $upstream_cache_status;
                proxy_cache_lock on;
                proxy_pass $REMOTE$request_uri;
                proxy_cache assets;
                proxy_cache_valid 1y;
                proxy_cache_key $request_uri$is_args$args;
        }
}

Dockerfile

FROM nginx:alpine
COPY default.template /etc/nginx/conf.d/default.template
CMD sh -c "envsubst "`env | awk -F = '{printf " \\$%s", $1}'`" < /etc/nginx/conf.d/default.template > /etc/nginx/conf.d/default.conf && nginx -g 'daemon off;'"

Start command

docker build -t fxproxy .
docker run -d --name=fxproxy -e REMOTE=http://10.10.0.2:30120 -p 80:80 -v $PWD/cache:/srv/cache fxproxy
