 Try accessing 10.10.31.31 (VIP) from the browser. You will see the backend server page. Disable one node, and you can still see the webpage. Check ADC HA status. The live node will become Master when the other one down.
+===== How two HA ADC nodes handle cache purge and cache sync? =====
+Caches will be synced between two HA ADC nodes.  When the backend LiteSpeed cache plugin sends purge request to the live ADC, such cache purge will be synced. Cache file for purge request won't be deleted at that time while it will be regenerated when a new request for that URL coming.  Cache purge will be synced automatically, While cache replication can be enabled or disabled at user's preference. To enable cache replication, please go to " ADC Web Admin Console >> Configuration >> HA >> Enable Replication for Cached Data >> Yes".
