Rick,
Why can't the variables be URL variables? I think creating them as URL
variables is actually your best bet. If you use a scope like session
or application, you are certainly looking at race conditions which
cause mysterious bugs like the ones you are describing. Consider the
following example:
<html>
<cfloop from="1" to="3" index="i">
<iframe src="filler.cfm?myvar=<cfoutput>#i#</cfoutput>">
</cfloop>
</html>
Now filler.cfm:
<html>
<cfoutput>#url.myvar#</cfoutput>
</html>
This code works perfectly, rendering three iframes with documents
containing the numbers 1, 2, and 3.
Hope this helps.
