Many mobile devices can access websites on the Internet. A mobile device running a web server application can host websites and provide services. For a first mobile device to access services on a second mobile device, the first mobile device needs the IP address of the second mobile device. The first mobile device sends a connection request to the second mobile device. The first mobile device receives, from the second mobile device, the network address of the second mobile device, identification of services that are available on the second mobile device, and a security token. The first mobile device selects a service and sends an HTTP or HTTPS request for the service to the network address of the second mobile device, and also sends the security token. The second mobile device authenticates the request based on the token and allows the first mobile device to access the selected service.
