CFlock

Hi guys I have been reading up on the CFlock tag and I was just wondering is it really important that i include it in my CF application for the session variables?

Thanks.

Yes, it is. If your application is large (lots of pages), consider duplicating
your session variables as locally scoped variables in Application.cfm and using
the local variables in your application. You must have a OnRequestEnd.cfm page
that is automatically executed when each page is run. OnRequestEnd.cfm copies
the locally scoped variables back to the session variables. And don't forget
to do this prior to any CFLOCATON tag. See code below.



<!--- In Application.cfm, duplicate session variables to local Request.Ses
variables --->
<cflock scope="Session" timeout="10" type="readonly">
<cfset Request.Ses = Duplicate(Session)>
</cflock>

<!--- OnRequestEnd.cfm contains the following. This code must also preceed
any CFLOCATION tag --->
<cflock scope="Session" timeout="10" type="exclusive">
<CFLOOP COLLECTION="#request.ses#" ITEM="i">
<cfset Session[i] = request.ses[i]>
</cfloop>

Thanks for your reply my application doesn't have many pages and i don't even have an OnRequestEnd.cfm could this cause many problems if not changed?
