 What are the benefits of LiteSpeed Web ADC?

LiteSpeed Web ADC is a 100% software solution, meaning it can operate anywhere: private dedicated hardware, hosted environment, the cloud, etc. Web ADC's nearly-instant on-demand scaling adapts to your business needs, even during unexpected traffic spikes, with a flexible subscription model. A highly efficient, security-conscious, cost-effective product, LiteSpeed Web ADC allows you to confidently support higher loads without incurring the cost of additional hardware.

 How should caching be handled with an ADC?

For best results, caching should be done at the ADC level.

Backend-server-level caching doesn't work for this reason: when requests come in to the ADC, we cannot guarantee which backend server will handle each one. The cache can easily become out of sync, when a purge request hits one server but not the others.

 Is a LiteSpeed Web Server required on the backend?

Its preferred to have LiteSpeed Web Server set up on the backend, however LiteSpeed Web ADC works with all web servers.

 Does LiteSpeed Web ADC support QUIC?

Yes, LiteSpeed Web ADC and LiteSpeed Web Server both support QUIC.

 How often does LiteSpeed Web ADC come out with new versions?

We do not have a standard release schedule. Our goal is to continue providing the most cutting-edge technology possibile, so new versions are released often. Check out our release log.
