If you're running CFMX you can create a simple wait() function that does
not consume server resources using the code Douglas posted.
If you're not on CFMX, you have a few options if you need to wait for a
specific period of time.
1. Go to the Developer's exchange on the Macromedia site and search for
wait. You should find a few custom tags that will allow you to do what
you need.
2. Output a 'please wait' page to the user with the following in the
<head></head> section:
<meta http-equiv="refresh" content="10">
3. Output a 'please wait' page to the user with the following in the
<head></head> section:
<script>setTimeout("location.reload()", 10000);</script>
The JavaScript and <meta> tag solutions rely on browser support, but
don't require a custom tag.
Depending on your situation, any of these 3 solutions may work.
