Migrated to CF9 and now have CFCACHE problems

I have been page caching on my site for years using this code:

<cfcache timespan="#CreateTimespan(10, 0, 0, 0)#" directory="D:/websites/mysite/cache/" stripWhiteSpace="true">

This worked great -  it would keep a cached copy in the cache directory and would stay cached for 10 days.
Good stuff!!

Now I've had to switch servers and up to CF9. I still want to cache my pages but I just cant seem to get it right.

I am now using this code

<cfcache timespan="#CreateTimespan(10, 0, 0, 0)#"  useQueryString ="true" stripWhiteSpace="true">

But the pages dont cache in the cache directory and they dont seem to load faster as if they were cached.

Am I doing his right?

Am I even caching the pages?

I'd like to keep a copy in my cache directory is that possible?
