## Open Parallels HTML5 Client To open Parallels HTML5 Client, enter its URL in an HTML5-enabled web browser. The URL has the following format: `https://[hostname].[domain]/RASHTML5Gateway` Where [Hostname] is the hostname of the computer where a Parallels RAS Secure Client Gateway is running. The `RASHTML5Gateway` part must be used as-is. The following is an example of a valid URL: `https://myserver.mycompany.dom/RASHTML5Gateway` You can obtain the URL in the RAS Console by navigating to Farm / Site / Gateways. Right-click a RAS Secure Client Gateway and click Properties, then click the HTML5 tab and copy the URL from the URL field. When you open the URL in a web browser, the login page is displayed. Specify the user name and password and click Login. What happens next depends on how the HTML5 connectivity is configured on the server side (see Enabling HTML5 Connectivity on the Gateway for details). The following describes the three possible scenarios.
