We are currently working on a fairly detailed blog posting which will go through all the major caching options available to us in ColdFusion 9 and their impacts.  Hopefully this will be completed by tomorrow, Monday January 25, 2010.  We will discuss the following caching options:

• Caching within ColdFusion
• Caching the data tier
• Caching the web-application tier
• Caching before the web-application tier

Caching is becoming more and more necessary as we scale out web applications; more soon.
