Everything at the edge.
LiteSpeed Web ADC is an application delivery controller that balances load, caches pages, terminates TLS and filters attacks — all in front of your web servers.
What Makes Web ADC Different
HTTP/2, QUIC and HTTP/3
Modern protocols at the edge for faster client connections.
Explore featureAutomationEasy Cluster Management
ZeroConf and cPanel integration simplify backend registration.
Explore featureSecurityLayer 7 Anti-DDoS
Filter attacks before they reach application servers.
Explore feature04Cross-Datacenter Replication
Replicate cluster state across sites for resilient delivery.
Explore featureCacheLSCache with ESI
Cache full pages while keeping personalized fragments dynamic.
Explore feature06Flexible Load Balancing
Choose routing algorithms and content-aware rules.
Explore feature07High Availability
Fail over to a healthy ADC when a node goes down.
Explore feature08Scales with Traffic
Multiple workers and SO_REUSEPORT spread connections across cores.
Explore feature09Server-Level reCAPTCHA
Challenge suspicious traffic at the edge.
Explore featureModern Protocols at the Edge
LiteSpeed Web ADC accepts HTTP/3 and QUIC traffic at the edge while routing to backends over the protocol that suits each application.
TLS termination and compression at the ADC reduce repeated work on backend servers.
- HTTP/3 and HTTP/2 client connections
- HTTPS and QUIC offloading
- Protocol upgrade and downgrade for backends
- HTTP/3 and QUIC
- TLS 1.3
- Brotli compression
- Layer 7 routing
