This action can be used to suppress the generation of a WebPageAddUrl function for particular HTTP requests. The recorder will then choose the next best way to record this request, usually a WebUrl function will be scripted instead, but it might also be another function (for example WebPageLink, WebPageUrl, ...) depending on circumstances.
This can be useful, because parsing rules never parse data from embedded objects of a web page. If a HTTP request is scripted by a WebUrl function call instead, it is possible to apply HTTP parsing rules to this request.
