Even if storing the items in the database, you will still need to
keep track of the user.
I personally set a variable called variables.id in application.cfm.
<CFPARAM NAME="variables.id" DEFAULT="">
On every link throughout the site I append that variable.
href="somepage.cfm<cfoutput>#variables.id#</cfoutput>"
When the person places the first item in their cart I set a test
cookie, set the variable to the cfid and cftoken and set
client.rollcount to 1.
<cfif not isdefined('client.rollcount') and page is "cart.cfm">
<cfcookie name="testcookie" value="1" expires="1">
<cfset variables.id = "?cfid=#client.cfid#&cftoken=#client.cftoken#">
<cfset client.rollcount = 1>
<cfelse>
<cfif isdefined('cookie.testcookie') and isdefined('client.rollcount')>
<cfset variables.id = "">
<cfelseif not isdefined('cookie.testcookie') and
isdefined('client.rollcount')>
<cfset variables.id = "?cfid=#client.cfid#&cftoken=#client.cftoken#">
</cfif>
</cfif>
This way, search engines can follow all the links. page= is a
variable I pass to all my different shopping cart templates. If the
template is cart.cfm, then I set the query string. Search engine
robots can't get to that page since it's a form submission.
I also (not to confuse you) set a variable called variables.idback
which is the same as variables.id except it starts with a & instead
of a ?. Then I use that on links where I need to pass a query string
other than cfid and cftoken:
href="somepage.cfm?page=checkout.cfm<cfoutput>#variables.idback#</cfoutput>"
