With HTML Access the client system does not require any software other than a supported browser. The View deployment must meet certain software requirements.

Note:

Starting with version 7.0, View Agent is renamed Horizon Agent.

Note:

For HTML Access 3.5 and earlier, iOS devices such as phones and tablets are not supported. VMware recommends that you instead use Horizon Client for iOS. If you must support HTML Access on these devices, do not install HTML Access 3.x. Instead use HTML Access 2.6, which is the default version installed with View Connection Server 6.1.1.

Remote desktops

  • HTML Access 4.0 requires Horizon Agent 7.0 or later, and supports all the desktop operating systems that Horizon 7.0 supports. For more information, see the topic "Supported Operating Systems for View Agent" in version 7.0 of View Installation.

  • HTML Access 3.5 requires View Agent 6.1 or later, and supports all the desktop operating systems that View 6.2 supports. For more information, see the topic "Supported Operating Systems for View Agent" in version 6.2 of View Installation.

  • HTML Access 3.4 requires View Agent 6.1.1, and supports all the desktop operating systems that View 6.1 supports. For more information, see the topic "Supported Operating Systems for View Agent" in version 6.1 of View Installation.

Pool settings

HTML Access requires the following pool settings, in View Administrator:

  • The Max resolution of any one monitor setting must be 1920x1200 or higher so that the remote desktop has at least 17.63 MB of video RAM.

    If you plan to use 3D applications or if end users will use a Macbook with Retina Display or a Google Chromebook Pixel, see Screen Resolution.

  • The HTML Access setting must be enabled.

Configuration instructions are provided in Prepare Desktops, Pools, and Farms for HTML Access.

View Connection Server

View Connection Server with the HTML Access option must be installed on the server.

HTML Access 3.5 requires View Connection Server 6.2. When you install View Connection Server 6.2, you must select the Install HTML Access option.

HTML Access 3.4 requires View Connection Server 6.1.1. After you install or upgrade to View Connection Server 6.1.1 and verify that your remote desktops and RDS hosts are running View Agent 6.1.1, you must run a separate HTML Access installer on View Connection Server instances.

When you install the HTML Access component, the VMware Horizon View Connection Server (Blast-In) rule is enabled in the Windows Firewall, so that the firewall is automatically configured to allow inbound traffic to TCP port 8443.

Security Server

View Security Server: The same version as View Connection Server must be installed on the security server.

If client systems connect from outside the corporate firewall, VMware recommends that you use a security server. With a security server, client systems will not require a VPN connection.

Note:

A single security server can support up to 800 simultaneous connections to Web clients.

Third-party firewalls

Add rules to allow the following traffic:

  • Servers (including security servers, View Connection Server instances, and replica servers): inbound traffic to TCP port 8443.

  • Remote desktop virtual machines: inbound traffic (from servers) to TCP port 22443.

Display protocol for View

VMware Blast

When you use a Web browser to access a remote desktop, the VMware Blast protocol is used rather than PCoIP or Microsoft RDP. VMware Blast uses HTTPS (HTTP over SSL/TLS).
