In case you missed it, on September 16, 2009, Citrix announced our much anticipated release of XenApp 5 Feature Pack 2. My colleague, Vinny Sosa, did an awesome job detailing the three categories of focus for the release in his blog post. Over the next few days, I will be sharing more of my thoughts about the HDX (High Definition Experience) features that will lay to rest any fears you have about performance and user experience with regards to hosted application delivery! I’ll talk about the why these features are important to our customers, and more importantly, what you need to enable and configure these features for your XenApp infrastructure.

The first topic I want to cover is HDX MediaStream for Flash. So, what is it and why is it important? Well, instead of using your XenApp server to process and render the Flash application or video (impacts your server scalability – bad), HDX MediaStream for Flash leverages resources available on the user’s Windows device. Thus, resulting in two key benefits: 1) users are happy (good) because they have a local like experience with the Flash content (no more A/V sync issues or video jitter), and 2) administrators can free up server resources to do more important things or accommodate more users. Needless to say, I’m very excited about this feature in Feature Pack 2. And hopefully by now, I’ve piqued your interest as well.

Ok, so… here is the even more exciting part – enabling HDX MediaStream for Flash for XenApp.

First, let’s look at the system requirements:

On your XenApp server,

  • XenApp 5 Feature Pack 2 for Windows Server 2003
  • Internet Explorer (7 & 8) with ActiveX support

On the user’s Windows client device, you’ll need:

  • Adobe Flash Player 10 installed
  • Citrix online plug-in 11.2

Second: enabling HDX MediaStream for Flash.

Well, once you’ve install XenApp 5 Feature Pack 2, HDX MediaStream for Flash is enabled on your XenApp server by default. That’s it – very simple! Now, if you need to disable this feature, you can do so through the Group Policy Object Editor.

And what happens if the user doesn’t have sufficient resources to render the Flash content locally? In that case, XenApp will intelligently fall-back to the server-side rendering that exists in XenApp prior to Feature Pack 2.

See? Short, sweet and simple. My next blog will cover HDX Plug-n-Play for USB storage, and a bit of an Easter-egg feature called Secure Clipboard control! So, stay tuned!
