The Cross session clipboard Preview can be enabled by creating the following registry entry on the VDA:

Open the Windows Registry Editor using regedit.exe.
Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Citrix\wfshell\Virtual Clipboard\CrossSessionClipboard\
Create a REG_MULTI_SZ value named CrossSessionFormats

redirection6

The CrossSessionFormats can be configured with a list of clipboard formats that will be tunnelled through Cross session clipboard. Each entry must be entered on a separate line.

As an example:

CF_TEXT

CF_BITMAP

Is correct, however the following is incorrect: CF_TEXT,CF_BITMAP

In the following example the CF_TEXT and CF_BITMAP clipboard items will be sent tunneled through cross session when copying these data formats from one session to another:

Cross session will need to be configured with the desired clipboard data formats on all VDAs that the user will want to share clipboard data to and from in order for cross session clipboard to function.

Cross session clipboard formats that are configured will be blocked from clients that do not have cross session support (CWA client prior to CWA for Windows 2507).

Both the sending as well as the receiving Citrix® session will need to have matching clipboard data formats configured for Cross session.

Clipboard content to be copied between sessions is only allowed if the clipboard data that needs to be copied between sessions matches. If the clipboard format is not configured for cross session on the receiving VDA, the clipboard transfer will be denied and a user will not be able to paste the data in the receiving citrix session.

Note:

Both VDAs do not need to have all configured cross session clipboard formats to match, however only formats that appear in both CrossSessionFormats configurations will be shared between sessions.

For example i

Note:

The Cross session configuration is for Session to session only. If configured it could change session to client behaviour based on the configuration set. Cross session clipboard will not change client to session clipboard. Client to session configuration is done solely through the client to session related clipboard policies.

If a user is connecting to Citrix sessions that are configured for Cross session clipboard, but their client does not support cross session (e.g. using a Citrix Workspace App version prior to 2507, or connecting from an unsupported CWA like CWA Linux), clipboard transfer of those formats listed in the cross session configuration, from the Citrix session to the client will be denied.
