Hello,
I have now tested this with Apache and ActivePerl. However, there are a few caveats. The script relies on the .htaccess file to force the expiry of old graphs. If you are using Apache under NT this is still OK, but IIS does not use the htaccess file. You need to ensure that the graphs directory is either set for the appropriate expiry times, or set to NEVER CACHE. After taking a look, it appears that in IIS you can only set expiry times for an entire directory at once. So, set the graphs directory to expire in 5 MINUTES.
Thanks
