Abstract: An extended reality (XR) system includes an XR server for generating XR environment data for an XR session defined by an XR session identifier; and a client application for operating on an XR device to present an XR environment to a user based on the XR environment data received from the XR server. The client application has a web browser configured to communicate with at least one web server. The web browser of the client application sends to the web server a content request comprising a content identifier and the XR session identifier that defines the XR session presented by the client application. The XR server receives from the web server additional information for the XR session defined by the XR session identifier; and changes the XR environment corresponding to the XR session identifier received from the web server based on the additional information received from the web server.
