There exists an hack to detect whether a browser is IE or not.

// feature detection based on Andrea Giammarchi's solution: http://webreflection.blogspot.com/2009/01/32-bytes-to-know-if-your-browser-is-ie.html
```var ie = !+"\v1"; ```

This hack is used by the latest version of swfobject and Uglifyjs is "breaking it".

```var ie = !+"\v1"``` uglified becames ```var ie=!1```
