Citrix Virtual Apps and Desktops

Bidirectional content redirection policy settings

The bidirectional content redirection section contains policy settings to enable or disable the client to host and host to client URL redirection. Server policies are set in Studio, and client policies are set from the Citrix Workspace app Group Policy Object administration template.

Though Citrix also offers host to client redirection and Local App Access for client to URL redirection, we recommend that you use bidirectional content redirection for domain-joined Windows clients.

Bidirectional content redirection requires Citrix Virtual Apps and Desktops 1808 or XenApp or XenDesktop 7.13 and later plus Citrix Workspace app 1808 or later or Citrix Receiver for Windows 4.7 and later.

Important

  • Ensure that redirection rules don’t result in a looping configuration. For example, client rules at the VDA are set to https://www.citrix.com, and VDA rules at the client are set to the same URL possibly resulting in infinite looping.
  • We support only domain joined endpoints.
  • URL redirection supports only explicit URLs (URLs displayed in the browser address bar or found using the in-browser navigation, depending on the browser). We don’t support link shorteners.
  • Bidirectional content redirection supports only Internet Explorer 8 through 11. Internet Explorer must be used on both the user device and the VDA.
  • The Internet Explorer browser add-on is required for Bidirectional Content Redirection. For more information, see Register browser add-ons.
  • No fallback mechanism is present if redirection fails due to session start issues.
  • If two applications with the same display name are configured with multiple StoreFront accounts, one display name in the primary StoreFront account is used to start.
  • Supports only Citrix Workspace app for Windows.
  • A new browser window appears only when the URL is redirected to the client. When the URL is redirected to the VDA and the browser is already open, the redirected URL opens in a new tab.
  • Supports embedded links in files including documents, emails, and PDFs.
  • This feature works on both desktop sessions and application sessions, unlike Local App Access URL redirection, which works only on desktop sessions.
  • If Local App Access is enabled for URL redirection (either at the VDA or client), bidirectional content redirection does not take effect.

Host to client and host to host redirection

Use Studio to configure the host to client (client) and host to host (VDA) redirection policies.

By default, bidirectional content redirection is Prohibited.

To enable bidirectional content redirection

When you include URLs, you can specify one URL or a semi-colon delimited list of URLs. You can use an asterisk (*) as a wildcard in the domain name. For example:

http://*.citrix.com; http://www.google.com

  1. Start Citrix Studio.
  2. Open the Bidirectional Content Redirection policy.
  3. Select Allow Bidirectional Content Redirection, choose Allowed, and OK. If you do not allow this option, you are unable to complete this procedure.
  4. Select Allowed URLs to be redirected to Client and specify a URL, a list of URLs, or choose the default value.
  5. Select Allowed URLs to be redirected to VDA and specify a URL, a list of URLs, or choose the default value.

For information about the client-side bidirectional content redirection configuration on the Citrix Workspace app, see Bidirectional content redirection in the Citrix Workspace app for Windows documentation.

Bidirectional URL redirection support has been added for Google Chrome and Microsoft Edge. Bidirectional URL redirection for Chrome and Edge requires:

  • Citrix Virtual Apps and Desktops version 2106 or later
  • Citrix Workspace app for Windows 2106 or later
  • Browser Redirection Extension version 5.0 or later

You must configure policies on Citrix Workspace app for Windows for redirection to work properly. For more information, see the Citrix Workspace app for Windows documentation.

To enable bidirectional URL redirection for Chrome and Edge, install Chrome or Edge on the VDA. Once installed, you can register the native host with the browser. Use the following command in the command line to register Chrome, Edge, and Internet Explorer:

"%ProgramFiles(x86)%\Citrix\HDX\bin\vdaredirector.exe" /regall

Note:

When using these commands on Chrome, the bidirectional content redirection extension installs automatically from the Chrome Web Store.

To register the native host for Chrome only, use the following command:

"%ProgramFiles(x86)%\Citrix\HDX\bin\vdaredirector.exe" /regChrome

To deregister the native host for Chrome, use the following command:

“%ProgramFiles(x86)%\Citrix\HDX\bin\vdaredirector.exe" /unregChrome

To register the native host for Edge only, use the following command:

"%ProgramFiles(x86)%\Citrix\HDX\bin\vdaredirector.exe" /regEdge

To deregister the native host for Edge, use the following command:

"%ProgramFiles(x86)%\Citrix\HDX\bin\vdaredirector.exe" /unregEdge

Copy and paste between session and client

To configure copy and paste functionality from a session to client, set the following policies:

  • Client Clipboard redirection to allowed.
  • Restrict Client Clipboard Write to restrict pasting all formats from clipboard to the client.
  • Client Clipboard Write Allowed Formats to make an exception for pasting files from clipboard to the client (Use format CFX_FILE to allow the feature).
  • Restrict Session Clipboard Write to restrict pasting all formats from the clipboard into the VDA session.
  • Session Clipboard Write Allowed Formats to make an exception for pasting files from clipboard to the VDA (Use format CFX_FILE to allow the feature).

Register browser add-ons

The Internet Explorer browser add-on is required for bidirectional content redirection.

You can use the following commands to register and unregister the Internet Explorer add-on:

  • To register the Internet Explorer add-on on a client device: <client-installation-folder>\redirector.exe /regIE
  • To unregister the Internet Explorer add-on on a client device: <client-installation-folder>\redirector.exe /unregIE
  • To register the Internet Explorer add-on on a VDA: <VDAinstallation-folder>\VDARedirector.exe /regIE
  • To unregister the Internet Explorer add-on on a VDA: <VDAinstallation-folder>\VDARedirector.exe /unregIE

For example, the following command registers the Internet Explorer add-on on a device running Citrix Workspace app.

C:\Program Files\Citrix\ICA Client\redirector.exe/regIE

The following command registers the Internet Explorer add-on on a Windows Multi-session OS VDA.

C:\Program Files (x86)\Citrix\HDX\bin\VDARedirector.exe /regIE

Google Chrome and Microsoft Edge

Note:

Google Chrome and Microsoft Edge are supported only on Browser Redirection extension version 5.0 or later.

Google Chrome and Microsoft Edge support bidirectional content redirection. The browser add-on is required for bidirectional content redirection.

See Host to Client and Host to Host Redirection to enable bidirectional content redirection with Google Chrome and Microsoft Edge.
