VMware Horizon View 5.2 HTML5 Access is a new way to access your virtual desktop using the Blast protocol.
Actually is not integrated in the standard Horizon View package, but you need to download the required packages from the Horizon View Feature Pack section:
In this pack is included also the Unity Touch feature to integrate more function and fast programs/documents access for mobile devices (for more info see also: VMware Horizon View Unity Touch is awesome).
For system requirements and installation instructions, see Using VMware Horizon View HTML Access and VMware Horizon View Feature Pack Installation and Administration.
Note that you have both a “server part” that must be installed on the Connection Servers and a “desktop part” that must be added in the virtual desktops (or on the golden image).
