Some Proxy- and VPN-Servers apply agressive caching, which may cause temporary issues with this and other websites.
In case you are affected by this, you can enable the CacheBuster to bypass these caches for this website.
This works by adding a unique "cachetime" parameter to each request. When enabled, the setting is stored in a Cookie.
If you're not experiencing any caching-problems, then no need to enable the CacheBuster.
