This tutorial allows you to detect if a user has the Flash player installed, but will not determine which version of the player it is. This method is suitable when you simply need FLash 4 or higher support. The idea behind this method of Flash detection is simple
We have 2 html pages index.html and mainpage.html

index.html has a flash movie that has the following code:
getURL ("mainpage.html");
If browser doesn't have the flash 4 (or higher) plugin you will stay on index.html which may contain a description of how to get the flash plugin, and if browser has the flash plugin you'll automaticly be redirect to mainpage.html (your main flash movie page).
