How to enable Server-Side content fetching in HDX MediaStream for Flash

This article describes how to deploy, configure, and confirm functionality of Server-Side Content Fetching (SSCF) in HDX MediaStream for Flash.


Server Side: Adobe Flash Player 10 or later Internet Explorer 7 or later HDX Capable Virtual Desktop Agent 4 or later, or XenApp Server (HDX MediaStream for Flash 1.1.0+)
Client Side
: Adobe Flash Player 10 or later Internet Explorer 7 or later Online Plug-in 11.2.2 or later


HDX MediaStream for Flash provides the ability to fetch and render Flash content on the endpoint, thereby reducing server load, and optimizing the end-user experience. There are some cases when the default client-side content fetching is not desirable, or functional. For example, the content might be referenced by the Flash Player using a network address that is internal to an organization (for example: http://mycorporation/video.swf).

Such a URL can only be resolved on the server, and server-side content fetching must be used. Perhaps the most common use case requiring HDX MediaStream for Flash server-side content fetching is an organization that restricts the network connectivity of their ICA client devices so that they can communicate only with their XenApp or XenDesktop servers. Such an organization would configure HDX MediaStream for Flash to use server-side content fetching for all Web sites.

Server-side content fetching is the exception and can be configured on a per-URL basis using a server-side configuration setting. In addition, server-side content fetching must be enabled on the client. Continue reading “How to enable Server-Side content fetching in HDX MediaStream for Flash”

Hotfix for XenApp 6.5 AppCenter

New Fixes in This Release

  1. When publishing a streamed application, if the .profile name differs from the parent folder name, the AppCenter incorrectly reports:

    “The above file name is not a valid Citrix streaming application profile.”

    [From DSCXAMx650W002][#LA0505]

  2. This fix improves the reliability of the AppCenter when custom administrators with permissions to “View Published Application and Content” navigate to Applications and then click Current Settings.

    [From DSCXAMx650W002][#LA1313]

  3. When multiple administrators make changes from different consoles at the same time, they might not be able to view each other’s changes unless discovery is run.

    [From DSCXAMx650W002][#LA1455]

  4. The AppCenter becomes unresponsive when trying to rename a published application while the Current Settings tab is active.

    [From DSCXAMx650W002][#LA1665]

  5. The AppCenter reports the product version to be Citrix Presentation Server 6.5.6682 and no hotfixes are displayed. The issue occurs when there is a server (listed alphabetically) in the farm that is configured for session-host only mode.
