This information is provided by an RMS technician when OLB is integrated.
The RMS Online Booking (OLB) software, interfaces directly with the RMS software to display search results and book reservations. These settings in the Control File Web Information screens work in conjunction with your web pages. RMS OLB uses a series of customizable template pages that are displayed in sequence according to the internet guest's step in the booking process. Preprocessor tags (#PREPROCESSOR#) are used to populate the template pages with relevant data from RMS. These preprocessor tags are TWIG tags and more information may be found at http://twig.sensiolabs.org/ . You may customize these template pages via FTP to your liking; as long as the preprocessor tags remain intact (see documentation provided to webmaster).
