LiteSpeed Web ADC FAQ
Is this a solution which can work with a control panels?
Not yet, but we are working on it to work on it.
IP fail-over setup available on ADC?
Not yet, but we are working on it. HA WebADC will have IP fail-over setup via Keepalived on Linux. If one ADC box is down, the other one will take over immediately. ADC has a keepalived manager in webAdmin. shared IP need to be configured via webadmin. fail-over works in the same way as Keepalived. If IPs exist on different interfaces, is that supported? It should not be any problem with multiple NIC, as long as Keepalived allows.
Does Web ADC handle backend nodes data synchronization?
Data synchronization across backend nodes is not a responsibility of the ADC. ADC only takes care its internal states. For backend nodes, you will need a shared storage for files and DB replication for databases. If DB HA is not required, you can setup multiple web nodes talking to one DB server.
Is ADC able to load balance MySQL?
For MySQL, ADC has Layer4 mode. It is not layer7, hence it can not route traffic at per-query level and cannot split read/write.
Rewrite rules for cache should be made on ADC or on the underlying web server(s)
If rewrite rule is used to control cache behavior, it needs to be applied to ADC, ADC will work with WordPress/Magento cache plugin, ADC will get the cache control related response headers set by the plugin.
Does ADC support mod_security rules?
Yes. ModSec engine in ADC is similar to the one in our web server.
