### Configure HTML5 Gateway The HTML5 tab is used to configure the HTML5 Gateway. Parallels HTML5 Gateway is a functionality built into RAS Secure Client Gateway that allows users to connect to Parallels RAS and open published resources from a web browser using the Parallels HTML5 Client. The client works similarly to a platform-specific Parallels Client, but does not require any additional software to be installed on users' computers or devices. All that users need is an HTML5-enabled web browser. This section describes how to configure HTML5 Gateway in the Parallels RAS Console. For the information about how to use it, please refer to the Parallels HTML5 Client chapter. Note: To use HTML5 Client, SSL must be enabled on a RAS Secure Client Gateway. When enabling the client, please verify that SSL is enabled on the SLL/TLS tab or on your network load balancer. Please also note that the HTML5 tab is only available if the gateway mode is set to "Normal". For more information, see Gateway Mode and Forwarding Settings. To configure HTML5 Gateway, click the HTML5 tab in the RAS Secure Client Gateway properties dialog and then set the options described in the subsequent sections. For the information on how to configure the HTML5 Client URL and how to access the client from a web browser, please Web Request Load Balancing.
