Agent can intelligently display or hide content from the server side. This means that the content is never downloaded to the browser at all, not just hidden from view. This results in faster page downloads! For example, load a large image gallery on desktop but then on mobile devices, you could display a single image. This would drastically improve performance for mobile users. The included Agent URL also allows you to control content by passing values dynamically through a URL query. This is a great way to build multi-language websites.
