About this release

Nov 01, 2017

Receiver for HTML5 is hosted on StoreFront servers and enables users to access virtual desktops and hosted applications from a web browser. Resources delivered by XenDesktop and XenApp are aggregated in a StoreFront store and made available through a Receiver for Web site. With Receiver for HTML5 enabled on the site, users can access desktops and applications within their web browsers without needing to install Receiver locally on their devices.

When used in conjunction with the centralized customization and branding capabilities of the StoreFront 3.0, users of this Receiver for HTML5 release will receive a centrally managed app and desktop selection experience from StoreFront. This is the same consistent user experience that can be received by the Windows and Mac desktop Receivers and Chrome web Receiver when associated with the StoreFront 3.0.

File Transfer

Receiver for HTML5 provides secure file transfer between a user device and virtual XenDesktop sessions. This feature uses a file transfer virtual channel instead of client drive mapping.

By default, users can:

  • Upload files from a local download folder or attached peripheral and seamlessly access the data from their XenDesktop sessions.
  • Download files from their XenDesktop sessions to a folder or peripheral on their user device.

Administrators can selectively enable or disable file transfer, uploads, or downloads through policies in Citrix Studio.


  • XenDesktop 7.6 or XenApp 7.6, with:
    • Hotfix ICATS760WX64022.msp on server OS VDAs (Windows 2008 R2 or Windows 2012 R2)
    • Hotfix ICAWS760WX86022.msp or ICAWS760WX64022.msp on client OS VDAs (Windows 7 or Windows 8.1)
  • To change file transfer policies: Group Policy Management (GPM) hotfix GPMx240WX64002.msi or GPMx240WX86002.msi on machines running Citrix Studio


  • A user can upload or download a maximum of 10 files at a time
  • Maximum file size:
    • For uploads:  2147483647 bytes (2 GB)
    • For downloads: 262144000 bytes (250 MB)

File Transfer policies

By default, file transfer is enabled. Use Citrix Studio to change these policies, located under User Setting < ICA\File Redirection. Consider the following when using file transfer policies:

  • Allow file transfer between desktop and client. Allows or prevents users from transferring files between a virtual XenDesktop session and their devices.
  • Upload file to desktop. Allows or prevents users from uploading files from their device to a virtual XenDesktop session.
  • Download file from desktop. Allows or prevents users from downloading files from a virtual XenDesktop session to their device.

Session Reliability

Receiver for HTML5 now includes improved session reliability to provide mobile users with uninterrupted access to apps and virtual desktops when moving between network access points. This functionality improves the user experience by ensuring a constant state of active connectivity, even when the user’s device power cycles when entering sleep mode.

Note: Sessions will only resume when network connectivity resumes after 180 seconds.

  • ICATS760WX64022
  • ICAWS760WX64022
  • ICAWS760WX86022
