What are the real performance issues with having global client variables
enabled?
I just did some testing and it seems HITCOUNT increases with each client
variable change on a different page within an app. What's the point of
Hitcount if it's updated everytime a client variable is changed? It doesn't
tell you how often someone visits your site, but rather how often your
client variables change. I mean has anyone found a use for this field? No
wonder your registry explodes if you keep this stuff in the registry....
Below is the code I used to test this.
<---Application.cfm--->
<CFAPPLICATION name="northwind" clientmanagement="yes"
clientstorage="northwind">
<---app_locals.cfm--->
<cfparam name="client.color" default="">
<cfparam name="client.text" default="">
<cfparam name="fuse" default="">
<---index.cfm--->
<cfinclude template="app_locals.cfm">
<cfswitch expression="#fuse#">
<cfcase value="1">
<cfinclude template="test_clientvar.cfm">
</cfcase>
<cfcase value="2">
<cfinclude template="test_clientvar_2.cfm">
</cfcase>
<cfdefaultcase>
<cfinclude template="test_clientvar.cfm">
</cfdefaultcase>
</cfswitch>
-----changes client.text to green and client.color to blue
<---test_clientvar.cfm--->
page 1<br><br>
<cfset client.color = "blue">
<cfoutput>
#client.color#<br>
#client.hitcount#<br>
</cfoutput>
<cfset client.text = "green">
<cfoutput>
<b>
#client.text#<br>
#client.hitcount#<br>
</b>
</cfoutput>
<a href="index.cfm?fuse=2">next</a>
-----changes client.text to blue and client.color to green
<---test_clientvar_2.cfm--->
page 2<br><br>
<cfset client.text = "blue">
<cfoutput>
#client.text#<br>
#client.hitcount#<br>
</cfoutput>
<cfset client.color = "green">
<cfoutput>
<b>
#client.color#<br>
#client.hitcount#<br>
</b>
</cfoutput>
<a href="index.cfm?fuse=1">next</a>
