NetScaler

=Basics=
 * A Netscaler is deployed in front of Server farm & functions as a Transparent Proxy between Client & server without requiring any client-side Configuration.


 * 1) ship
 * 2) show connectiontable

OR
 * 1) config ns
 * 1) set ns config -Ipaddress  -netmask


 * 1) add ns ip  -mgmtAccess [Enabled|Disabled] -type MIP


 * Adding Virtual Server automatically creates a VIP
 * VLAN tagging does not propagate in NS HA Pairs
 * Can create null routes to prevent routing loops


 * 2 interfaces should not be plugged into same port or vlan unless using link aggregation


 * No IP to Interface mapping => Floating IP config
 * Why? In HA, when Primary failes, secondary takes over, no loss of Service.

- Configure the VIP for the same Hostname - Use URL Transformation to achieve the same
 * When the Backend Application expects request for a specific Hostname or redirect you to that hostname, Netscaler should be configured as below:
