Hi:

I have a hosted site with 2 different domains pointing to it, example: [www.a.com and [URL=“http://www.b.com”]www.b.com](http://www.a.com)

Is there anyway to read the url where the user came from in flash? I could change my flash movie according to the url of the user…

In ASP i use:

```auto
[FONT=Calibri]Request.ServerVariables("HTTP_HOST")[/FONT]

```

Thanks
