Found an interesting article on the Apple Developer’s Connection that talks about the benefits of using Object detection to determine a user’s browser. The article talks about the many pitfalls of using the more common “browser-sniffing” method of searching the Navigtor object to determine version info.
From the article:
Browser sniffing Ñ the task of inspecting navigator object properties for version information Ñ has become largely unmanageable given the browser version permutations available today. This article presents details on an alternative solution Ñ object detection Ñ that frees JavaScript developers from most of this versioning mess.
