On page load it counts ten seconds and going to another page

Hi !

How can I do a function that automatically, after the page loads, it counts ten seconds and going to another page, for instance: index.aspx ? With the current window.


Thanks,
Cesar

<META HTTP-EQUIV=Refresh CONTENT="10; URL=index.aspx">

Thank you! :)
I have put it between head tags, I suppose that is it place.
