Abstract: A method, web server (13) and web browser (15, 70) for allowing cross-communication between first and second areas of a primary web page respectively sourced by first and second content providers. First and second areas of the primary web page are allocated, and in the second area of the primary web page there is embedded a link to a secondary web page provided by the first content provider and containing a link to content from an unrestricted content provider, thus enabling any content thereof to be loaded to the second area within the primary web page. The primary web page may be encoded using a web marker language and a first object may be located at a desired location with respect to the web page, so that when the first object is displayed by a client machine (11) having a web browser (70) in mutual association with the web page the first object is spatially coordinated with a second object in the web page. Code is included in the web marker language of the web page, for displaying a reference object.
