Citrix HDX Adobe Flash Redirection

Citrix Flash-Redirection allows us to redirect Adobe Flash playback to be rendered on a compatible end-point.This technique ensures an optimal experience with the end-point taking the processing hit as opposed to the CPU on the VM or server.

Flash Redirection Set-up and Configuration
In order to ensure Flash redirection can occur the following are required.

1)Adobe Flash player Installed within the VM or Xenapp server host.

2)Adobe Flash player Installed on the end-point (for IE or other depending on your browser)

3)Citrix Receiver Client (V13 or newer for Gen2 Flash redirection)

4) Flash Redirection enabled in Citrix Policy (Default=Enabled)

5)Enable Flash Optimisation on the end point in the Receiver desktop viewer preferences

Testing its working

Once enabled we need to ensure that everything is working as expected. 

The HDX monitor tool from Citrix is great for this as it can show if Flash redirection is enabled and active.

To Test the experience visit a decent flash website. I found this one pretty good as it provide statistics on the playback experience. This video playback will resize based on the available bandwidth.

Note : Newer IE Browsers failing to perform Flash Redirection in Citrix Sessions

For Internet Explorer 11 the following may be required,

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\HdxMediaStreamForFlash\Server\PseudoServer

Add the entry named IEBrowserMaximumMajorVersion with a DWORD value = 11 (decimal). The hexadecimal equivalent is 0x0000000b
