For the same reason, it is advisable to keep Scalelite on a different machine and
to provide a HA setup for the proxy server (i.e. using IP failover or Anycast).
Please monitor your setup carefully.
### Caching the HTML5 Client on the Proxy
You may cache the BBB HTML5 client javascript and css files and other assets on
the proxy. This reduces network traffic on the BBB server especially if many
clients join in a short period of time.
On the proxy server add the following configuration to the nginx configuration:
```
proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=bbb:10m max_size=1g
inactive=60m use_temp_path=off;
```
For each BBB Server add the following snippet on the proxy:
```
location ~* ^/bbb-01/html5client/.+\.(ico|css|js|gif|jpeg|jpg|png|woff|ttf|otf|svg|woff2|eot)$ {
proxy_pass https://bbb-01.example.com;
