Due to the nature of travel reservations, and the physical locations of the PCI Booking servers, travelers creating reservations and entering card details are often substantially geographically separated from the PCI Booking card capture hosting location.
To combat the issue of page loading times increasing as distance from server to traveler grows, iFrame is now supported by a Content Delivery Network (CDN), a network of geographically dispersed servers designed to deliver cached data to the traveler from the nearest server. The use of CDN ensures the best possible user experience by decreasing latency.
To learn more about how to integrate a CDN into your solution please see the technical documentation.
