Puffin Cloud Browser is the client app that accesses the cloud server which runs the web browser. The Puffin client app and the Puffin cloud server do not communicate in HTTP protocol and the data exchange is not in HTML format. The Puffin client app is like the remote desktop client and the Puffin cloud server is like the remote desktop server. Puffin Cloud Browser gives the audience the illusion of a web browser but it is not, in reality, a web browser. Puffin Cloud Browser can only "display" the web content rendered on the cloud servers but can't "render" the web content itself on the client devices.
