Load intro page before index

I would like to load an ind开发者_运维百科ex.html file for 3 seconds just before my usual index.asp file. How can I do it?

THANKS!

Assuming you server is configured to prioritise the loading of index.html, you could use JavaScript to load a subsequent page after a given time interval.

You don’t really want to do this though do you? It’s very bad form. The JavaScript redirect would leave behind any search engine crawlers and other robots.
