Introducing the Web Interface
The Web Interface provides users with access to XenApp applications, content and XenDesktop virtual desktops. Users access their published resources through a standard Web browser or through the Citrix XenApp plugin.

What’s New in Web Interface 5.2

• XenApp VM hosted apps. XenApp now has the capability to deliver online applications from virtual machines. This enables you to publish applications that are incompatible with or not yet validated for Terminal Services, or applications that are not supported for installation on Windows Server operating systems.
• XenDesktop user roaming. You can associate user groups with specific XenDesktop farms to provide a consistent experience for users, regardless of their current location or the server to which they are logging on. This enable users who travel abroad on business, for example, to log on to a local Web Interface server and automatically receive desktops in their native language from a XenDesktop farm in their home country.
• Disaster recovery. You can specify XenApp and XenDesktop server farms for emergency use when users cannot access any of their production farms, perhaps due to a power failure or network outage. This enables you to make provisions to deal with the loss of access to all production servers so that line-of-business applications or desktops do not suddenly become unavailable.
• New management console. The Access Management Console snap-in for Web Interface for Microsoft Internet Information Services is replaced with a standalone Microsoft Management Console (MMC) 3.0 snap-in. The new Web Interface Management Console is installed automatically when you install the Web Interface on Windows platforms.
• Secure Ticket Authority redundancy. You can configure multiple redundant Secure Ticket Authorities (STAs) for users accessing their resources through Access Gateway or Secure Gateway. This enables you to mitigate against the possibility of the STA becoming unavailable midway through a user’s session, preventing reconnection to the session. When redundancy is enabled, the Web Interface attempts to obtain and deliver to the gateway two tickets from two different STAs. If one of the STAs cannot be contacted during a user session, the session continues uninterrupted using the second STA.
