[CFCDev] Race Conditions when scoped in the Application variable

[Andrew Scott]

Ok I am looking at a solution where I am keeping track of certain details that users do on the website. I was looking at creating it in the application scope. But I am unclear on a few things.   If I set up the scop in this manner.   <cfset Application.userFactory = CreateObject(‘component’,’com.framework.user’) />   Now through the code I will make reference to it like such.   <cfset Application.userFactory().AddUser(UserObject) /> <cfset Application.userFactory().DeleteUSer(UserObject) />   Now what I am not clear on is the internals of this, for example. The user object has a structured array that contains the information for all users logged into the system, and other tid bits of information. My question is, should I be locking access to variables when setting inside or not?   This is where I am a little unclear, I have had a look at the Mach-II framework and it doesn’t seem to do this. Except when setting the application.userfactory in the application scope to begin with.   Could someone give me a little more run down on this, as well as hopefully clear the process up a little more for me as well.     Regards Andrew Scott Analyst Programmer CMS Transport Systems Level 2/33 Bank Street South Melbourne, Victoria, 3205 Phone: 03 9699 7988  -  Fax: 03 9699 7976 Quote: A pessimist thinks everybody is as nasty as himself, and hates them for it. - George Bernard Shaw ------------------------------------------------------------------------------------------------------ ---------------------------------------------------------- You are subscribed to cfcdev.
