* and the the URI where the content of the next page comes from.
* This data is needed for the js part in main.js.
* Note: infinite scroll does only work for the network page (module)
*
* @param string $module The name of the module (e.g. "network")
* @return array Of infinite scroll data
* 'pageno' => $pageno The number of the actual page
* 'reload_uri' => $reload_uri The URI of the content we have to load
