Using NetScaler Gateway for Content Switching Policies with Legacy Citrix Clients
The age-old problem of Legacy Citrix Receiver client access through a common NetScaler Gateway has now been solved!
Starting with NetScaler 10.5 Build 51.1017.e+,you can now can create and bind Content Switching Policies directly to NetScaler Gateway VServers.
Connections destined for the Gateway are terminated and processed as normal, but before any actions are invoked on the session, the policy engine checks to see if any Content Switching policies are bound which may apply. If the conditions defined in the policy are satisfied, connections are sent to the target Load Balancing VServers defined in the applicable Content Switching Policy action.
Although this particular enhancement was developed for ShareFile and XenMobile clients, another primary use case is to identify down-level Citrix clients such as PNAgent or embedded custom clients found in Thin Clients. The enhancement allows you to simplify your deployment design for these clients by leveraging the same DNS namespace, IP, and SSL Certificate already in place for modern Receiver and Browser clients. This was previously not possible as the down-level client authentication methods are incompatible with those required by the NetScaler Gateway VPN VServer. These connections normally have to terminate at the Web Interface services site, or legacy services URL on StoreFront.
