iFrame timed redirect

[techoveride]

I am using an iFrame on a webpage and I am trying to figure out how have the iFrame change on a timed redirect. But I only want it to change from the intro page to the main page and not change after that.

Any help would be appreciated.

In the page HEAD code that first loads into the iframe:

<meta http-equiv="refresh" content="5; url=main.html" />

where "5" = the number of seconds until the refresh and "url=" the main page's file name.

Do not include the refresh meta tag in the main page HEAD code and it will stay put.
