Read PageFile to identify the file, if any, that the associated Web page module uses when generating its Web page. This can be the Web page that the Web page module returns, or it can be a template that the Web page module modifies to generate its final product. 

In TAbstractWebPageInfo, the property read access method for PageFile is abstract pure virtual. Descendant classes must override the protected GetPageFile method to provide an implementation for this property.
