## Configure HTML5 Client The HTML5 Client is a part of RAS Secure Client Gateway. To be used by end users, the HTML5 Gateway must be enabled and configured in the RAS Console as described in Configure HTML5 Gateway. Session persistence based on a cookie RAS HTML5 Client session persistence is normally set by user's IP address (source addressing). If you can't use source addressing in your environment (e.g. your security policy doesn't allow it), you can use the Session Cookie to maintain persistence between a user and a server. To do so, you'll need to set up a load balancer that can use a session cookie for persistence. The cookie that you should use is ASP.NET_SessionId. If you are using a load balancer that doesn't use ASP.NET, you can specify a different cookie on the Web Requests tab of the RAS Secure Client Gateway Properties dialog. For more information, see Web Request Load Balancing.
