Deploying a LightSwitch HTML application is an easy task. In fact, you deploy a LightSwitch HTML app to a web server the same way you would do for the Silverlight client. This is important to mention before talking about authentication in the HTML client. Since I assume you already have some experience, I'll describe this procedure in just a few quick steps.
Remember that the URL for the HTML client has the following form:
Notice that the URL ends with htmlclient. This is the default when you create a project using the LightSwitch HTML Application template. If you add the HTML client to an existing project that already has the Silverlight client, you can specify a different name, which will also be the termination of the URL.
