process?
It seems that whenever I enable a "Who's online" or homegrown advanced
session information features on my site, the server eventually degrades
etc... Other than a CFLOCK which I know I need to add in (and will) is
there any other "red flags" about doing something like this which I
should be aware of?
I am trying to determine if there are any known issues with CFMX 6.1
with doing something like that.
Here's (in cf-nevercompiled-pseudocode) what I'm doing: (names of files
are made up for this email...)
<!--- Act_OnLoginSuccessful.cfm --->
<Cfset session.state = structnew()>
<Cfset session.username = SomeLoginQuery.username >
<Cfset structinsert(session.username,session.state)>
<!--- App_globals.cfm or application.cfm --->
<Cfparam name="application.states" default=structnew()>
<Cfif isdefined("session.state")>
<Cfset session.state.last=now() >
</cfif>
<!--- Dsp_WhosOnline.cfm --->
<cfset MyStruct=StructCopy(Application.states)>
<Cfloop list=structkeylist(mystruct) index="key">
<Cfif
datediff("n",structfind(structfind(mystruct,key),"last"),now()) gt 30>
<CFset structdelete(application.states,key)>
</cfif>
<Cfelse>
Display something here about #key# and
#structfind(structfind(mystruct,key),"last")#
</cfif>
</cfloop>
