A user session ends after user processes and visible windows end (for example, when a user exits from an application, the session ends). You can use session linger to provide a better user experience by eliminating the launch delay between applications.
To use session linger for named user sessions, configure the following Citrix User policy settings:
Linger Terminate Timer Interval specifies the number of minutes a session remains active after the last application terminates.
XenApp 6.5 brings a host of features and benefits that most companies will need as the technology continues to evolve and user requirements continue to expand.Here are the list of features and explanation given below:
Simplified Installation Single Management Console Worker Groups Policies and GPO Integration Merchandizing Server and Windows Receiver HDX Provisioning Server MultiStream ICA Integration with Desktop Director Pre-launch, Session Linger, and Fast Reconnect Controller and Session-Host Feature

XenApp 6.5 Available Now! These are exciting times for desktop virtualization. The industry is growing and Citrix is leading the charge. The XenDesktop product line is getting plenty of well-deserved attention, but today Citrix is also announcing exciting new enhancements for XenApp 6.
To pre-launch applications to user devices Use the pre-launch feature to reduce application launch time at high-traffic periods. For example, if your environment includes a large number of users who launch the same application within a ten-minute time-frame, the rapid succession of logon requests can overwhelm servers and slow down application launch for all users. The pre-launch feature allows a pre-launch session to be created when a user logs on, or at a scheduled time if the user is already logged on.
Configuring Session Reliability
Session Reliability keeps sessions active and on the user’s screen when network connectivity is interrupted. Users continue to see the application they are using until network connectivity resumes.
This feature is especially useful for mobile users with wireless connections. Take, for example, a user with a wireless connection who enters a railroad tunnel and momentarily loses connectivity. Ordinarily, the session is disconnected and disappears from the user’s screen, and the user has to reconnect to the disconnected session.
For those of you that are not aware, NetScaler Insight Centre is a Virtual appliance (VPX) which collects information about traffic flowing through your NetScaler devices. The information it collects can be used to present the data in a series of reports. They can be used to monitor both Web traffic as well as ICA and VPN / Access Gateway sessions. The collection of this information is known as Web Insight in the case of Web Traffic and HDX Insight for ICA/VPN.
Enabling Thin Provisioning is an option during XenServer Installation. Thin Provisioned disks are a pre-requisite for using the new XenServer feature IntelliCache.
If you missed this option when creating the machine storage repository it is possible to enable the feature from the CLI afterwards. This will however destroy your Storage repository as the file format for Thin Provisioning is EXT3 as opposed to the standard LVM.
In some instances this method may still however be useful.
Postitives about Citrix:
Client support – I’d be more surprised if you can find a platform XenDesktop isn’t supported on. XenApp/XenDesktop uses the Citrix ICA protocol and therefore the Citrix Receiver. There’s client’s for Blackberry, Windows 8, iOS, Linux and Android just to name a few. Integration with XenApp – A VDI solutions is not just about virtualizing the desktop but also about providing access to applications. XenDesktop shares a lot of common backend infrastructure and features with XenApp.
With the recent increase in demand for XenServer as the primary virtualization technology for the datacenter, I frequently hear from XenServer Admins and Citrix Cloud Admins that they love the number of features included in the different editions of the XenServer product. The request often turns to “Where can I get more training on the advanced features?” This prompted me to compile a simple “How To…” post providing links to videos and training resources for the XenServer product line.
How many users do you have? Are any of them currently using XenApp? Will you virtualise your servers? What do your users do? What applications do they use What do the applications do? Where are the users based? Where is the application infrastructure and data located? What printing do they do? How do users work remotely? Is high availability a key requirement? Will you consider user virtualisation and application virtualisation? Web Interface is going EOL in the not too distant future Have you considered XenDesktop 7?
