These scripts follow the same architecture as the Flash Detection / Redirection scripts. They offer a similar range of flexibility and cross-browser support.
This script does a basic Quicktime version detection and is used by the other Quicktime scripts. It gives you the flexibility to do whatever you like based on the visitor's level of Quicktime support.
When you have separate HTML-only and Quicktime-enhanced sites, this script can act as an invisible gateway (the detection is seamless and the page is removed from the history of the browser) routing the visitor into one of the two sites.
To improve the preformance when detecting on several pages, the result of the first Quicktime detection is stored in a cookie which can be checked on other pages.
