FAQ
Common questions and answers about CDN Engine.
How is the node count calculated?
Node count refers to the number of servers where you deploy CDN Engine edge nodes. For example, if you have 5 servers for cache acceleration, you need to purchase a license that supports at least 5 nodes.
Which operating systems are supported?
CDN Engine is developed based on Go language and supports Linux (CentOS, Ubuntu, Debian, etc.) and macOS. Deployment on Linux is recommended for best performance.
How to apply for HTTPS certificates?
The system has built-in automated integration with Let's Encrypt. You only need to bind the domain in the backend, and the system will automatically apply for, verify, and renew SSL certificates without manual intervention.
What if my business scale expands?
You can increase the node count license at any time. Our billing model supports elastic scaling, just pay for the additional nodes. For large-scale enterprise needs, our sales team will provide you with a custom solution.
Do you provide deployment assistance?
Commercial license users are provided with detailed documentation and standard technical support. For large-scale deployments or custom needs, we can assist you with remote installation and configuration optimization.
How is data security guaranteed?
We attach great importance to data security. CDN Engine supports various security strategies such as WAF protection, hotlink protection, and IP black/white lists. At the same time, the management backend supports two-factor authentication (2FA) to ensure account security.
Which cache policies are supported?
Supports various cache rules based on file extensions, directories, full paths, etc. You can customize cache expiration time (TTL), and support advanced configurations such as forced caching and ignoring parameter caching.
Does WAF protection support custom rules?
Yes, in addition to the built-in OWASP core rule set, you can also write custom WAF rules according to business needs, supporting regex matching, IP banning, CC attack defense, etc.
Is an API interface provided?
We provide a complete RESTful API covering all functions such as domain management, certificate management, and statistical analysis, facilitating your integration of CDN Engine into existing O&M systems.
Is real-time logging supported?
Yes. You can view access logs, error logs, and WAF interception logs in real-time. It also supports pushing logs to external storage such as Elasticsearch, ClickHouse, or NATS.
What is the refund policy?
Due to the special nature of software products, refunds are not supported after license purchase. This product does not provide a trial version, please confirm your needs carefully before purchasing.
How to get software updates?
We provide an integrated cloud update service that automatically completes compilation and packaging for all your Master and Node nodes. In addition to smooth upgrades of the core program, this service is also responsible for automatically updating static resources such as License authorization, GeoIP databases, and WAF rule libraries, ensuring your system is always up-to-date and secure.
