Assembling and Installing Third-Party Plug-ins—Example: Citrix
The open framework of the security appliance lets you add plug-ins to support third-party Java
client/server applications. As an example of how to provide clientless SSL VPN browser access to
third-party plug-ins, this section describes how to add clientless SSL VPN support for the Citrix
Presentation Server Client or Citrix Web Interface (for XenDesktop).
Caution Cisco does not provide direct support for or recommend any particular plug-ins that are not redistributed
by Cisco. As a provider of clientless SSL VPN services, you are responsible for reviewing and
complying with any license agreements required for the use of plug-ins.
With a Citrix plug-in installed on the adaptive security appliance, clientless SSL VPN users can use a
connection to the adaptive security appliance to access Citrix MetaFrame or Web Interface services.
A stateful failover does not retain sessions established using the Citrix plug-in. Citrix users must
reauthenticate after failover.
To provide access to the Citrix plug-in, follow the procedures in the following sections.
