CFWheels Plugin: Bypass Cache for Logged in Users
<cfcomponent>
<cffunction name="init">
<cfset this.version = "1.0,1.0.1,1.0.2,1.0.3,1.0.4,1.0.5,1.0.6,1.1,1.1.1,1.1.2,1.1.3,1.1.4,1.1.5,1.1.6,1.1.7,1.1.8,1.3.0,1.3.1,1.3.2">
<cfreturn this>
</cffunction>
<!---
Just added isNull(session.user) to 2 conditions so cache doesn't run for logged in users -- Per is working on fixing this for 1.3.3 or 2.0
