No, that's not correct. variables.user.username will be "blah blah, overwriting original value". session.user will still be the original value. If session.user is a simple value, a string, "Joe Blow", then using... <cflock scope="session" type="readonly" timeout="10"> <cfset variables.user = session.user> </cflock> <cfoutput>#variables.user#</cfoutput> ..will be fine without locking the output because variables.user is a new variable. However, if session.user is a "complex" variable, a query, array, etc., then using... <cflock scope="session" type="readonly" timeout="10"> <cfset variables.user = session.user> </cflock> <cfoutput query="variables.user">#variables.user.username#<br></cfoutput> ..will need to be locked because you haven't created a new variable. You have simply created a "pointer" to session.user. This will create a "new" variable called variables.user rather than a pointer: <cflock scope="session" type="readonly" timeout="10"> <cfset variables.user = duplicate(session.user)> </cflock> <cfoutput query="variables.user">#variables.user.username#<br></cfoutput> or for version 4.01... <cflock name="some_unique_name" type="readonly" timeout="10"> <cfwddx action="cfml2wddx" input="#session.user#" output="newvariable"> <cfwddx action="wddx2cfml" input="#newvariable#" output="variables.user"> </cflock> <cfoutput query="variables.user">#variables.user.username#<br></cfoutput> Simple, yes?
