Right now the .kml files that I use for a Google Maps implementation on my site are being cached for 7 days because the Cache-Control header within IIS7 is set to 7 days (as per these instructions).
I could use version control to update the .kml files when changes are made, but I would rather not because other people might want to refer to them.
Can I configure IIS7, or make a configuration change to the .kml file in order to remove the caching, or set it to a very short period?
