Originally, to detect the Flash Plugin, it took complex JavaScript which took ages to code. This didn't always work because not all browsers are JavaScript enabled. This tutorial explores a way to detect if someone viewing a webpage has the plugin, using Flash itself.

How it works

For this to work, the index.html file (default file) must include two main things:

  1. An HTML Meta Tag
  2. A small Flash file
The Meta Tag

The meta tag refreshes the HTML file after a certain number of seconds, and goes to the non_flash file. Here is the coding:

<%lt%>META HTTP-EQUIV="Refresh" CONTENT="seconds_until_refresh; URL=non_flash_url"<%gt%>

This is placed in the head of the document.

Note: Make sure you do not change any of the coding (ie quotation marks etc) except for the number of seconds (replace seconds_until_refresh), 5-10 is a good amount, and the next URL (replace non_flash_url). If you change anything else, it may not work
