- Configure Flash Redirection on the server
- Configure Flash Redirection on the user device
To configure Flash Redirection on the server, use the following Citrix Policy settings:
The Citrix policy setting Flash default behavior establishes the default behavior of Flash acceleration. By default, Flash Redirection is enabled except for Windows 8 and Windows Server 2012 VDAs, where it is not supported.
To override this default behavior for individual web pages and Flash instances, use the Flash URL compatibility list setting.
Three options are available:
|Block Flash player||Flash Redirection and server-side rendering are not used. The user cannot view any Flash content.|
|Disable Flash acceleration||Flash Redirection is not used. The user can view server-side rendered Flash content if a version of Adobe Flash Player for Windows Internet Explorer compatible with the content is installed on the server.|
|Enable Flash acceleration||Flash Redirection is used; this is the default.
Important: This option requires that the Enable HDX MediaStream Flash Redirection on the user device Group Policy Objects policy setting is enabled on the user device.
Flash intelligent fallback is enabled by default, to detect instances of small Flash movies (such as those frequently used to play advertisements) and to render them on the server instead of redirecting them for rendering on the user device.
Flash intelligent fallback does not cause any interruption or failure in the loading of the web page or the Flash application.
To redirect all instances of Flash content for rendering on the user device, disable the Flash intelligent fallback policy setting.
By default, Flash Redirection downloads Flash content to the user device, where it is played. The Flash server-side content fetching URL list policy setting allows you to specify websites whose Flash content can instead be downloaded to the server and then transferred to the user device for rendering. This setting works with the Enable server-side content fetching setting on the user device and is primarily intended for use with Intranet sites and internal Flash applications. It also works with most Internet sites and can be used when the user device does not have direct access to the Internet (for example, when the XenDesktop server provides that connection).
To improve the appearance of the web page when using Flash Redirection, use the Flash background color list policy setting. This enables you to match the colors of web pages and Flash instances.
