z When GSLB feature is enabled, the DNS response generated by
NetScaler runs through the GSLB decision-making mechanism.
This mechanism re-orders the IP addresses in the list based on the
health metrics of each IP address.
z When GSLB feature is disabled, the IP addresses are not
re-ordered. The system will maintain a list of IP addresses in the
order in which they were configured on the NetScaler 9000
system.
z Proximity-based GSLB - The Proximity base GSLB feature cannot be
enabled separately. The license hierarchy is:
z Proximity needs base GSLB and base GSLB in turn requires LB.
For GSLB, the DNS support to add domains is required.
So for the Proximity based GSLB to work, you need to have Base
GSLB, Proximity based GSLB, LB and DNS licenses.
z Web Logging (WL): No Web logging will be done, that is, the log files
are not created.
z Surge Protection (SP)- The Surge Protection feature is not triggered.
z SSL VPN – The SSL VPN feature is enabled by default for 5 licensed
users. If the number of concurrent user sessions exceeds this limit then
NetScaler returns the error message “SSLVPN - Number of users
exceeded.” Additional user packs are available as a means of boosting the
number of concurrent user sessions supported.
z Integrated Cache or Application Caching – To trigger Static and Dynamic
caching, the user has to enable the Integrated Cache feature. When the
Integrated Cache feature is enabled, basic Static caching is performed. To
cache dynamic contents, the user has to configure Dynamic caching in the
NetScaler 9000 system.
2.9 Autodetect Service
When the NetScaler 9000 system is deployed in transparent mode, it provides
autodetect service where it automatically detects the backend web servers.
Some of the scenarios are:
