19.  The Citrix NetScaler product is an application switch that performs application-
specific traffic analysis to intelligently distribute, optimize, and secure Layer 4-
Layer 7 (L4-L7) network traffic for web applications.
 It has switching feature. When deployed in front of application servers, a
NetScaler ensures optimal distribution of traffic by the way in which it directs
client requests.
 NetScaler security and protection features protect web applications from
application-layer attacks.
 A NetScaler allows legitimate client requests and can block malicious requests.
 It provides built-in defenses against denial-of-service (DoS) attacks and supports
features that protect applications against legitimate surges in application traffic
that would otherwise overwhelm the servers.

20.  A NetScaler resides between the clients and the servers, so that client requests
and server responses pass through it.
 In a typical installation, virtual servers (vservers) configured on the NetScaler
provide connection points that clients use to access the applications behind the
NetScaler.
 In this case, the NetScaler owns public IP addresses that are associated with its
vservers, while the real servers are isolated in a private network.
