i think i read this wrong. you WANT people to be able to jump from one
server to the other during a session. Well then, client variables to the
rescue. you could probably mimic with session variables:
in your database create a table that has these columns
CDATA
------
cfid char(100)
app char(64)
data text ** note in msaccess, use memo
Application.cfm
===============
<cflock timeout="10" throwontimeout="No" type="READONLY">
<cfset request.thissession = "#session.cfid#:#session.cftoken#">
<cfset request.thisapp = application.applicationname>
</cflock>
<cfquery name="GetSessionInfo"
datasource="#request.dsn#"
username="#request.username#"
password="#request.password#">
select
data
from cdata
where cfid = '#request.thissession#' and app = '#request.thisapp#'
</cfquery>
<cfset temp = request.session1 = StructNew()>
<cfif GetSessionInfo.RecordCount NEQ 0>
<cfloop index="i" list="#GetSessionInfo.data#" delimiters="##">
<cfif trim(i) NEQ "">
<cfset a = ListGetAt(i, 1, "=")>
<cfset b = ListGetAt(i, 2, "=")>
<cfset temp = StructInsert(request.session1, a, b)>
</cfif>
</cfloop>
<cfelse>
<cfquery name="InsertSessionInfo"
datasource="#request.dsn#"
username="#request.username#"
password="#request.password#">
INSERT INTO CDATA
(cfid, app)
VALUES
('#request.thissession#', '#request.thisapp#')
</cfquery>
</cfif>
Onrequestend.cfm
================
<cfset request.thisdata = "">
<cfloop collection="#request.session1#" item="i">
<cfset request.thisdata = request.thisdata & i & "##">
</cfloop>
<cfquery name="UpdateSessionInfo"
datasource="#request.dsn#"
username="#request.username#"
password="#request.password#">
UPDATE CDATA
SET
data = '#request.thisdata#'
WHERE where cfid = '#request.thissession#' and app =
'#request.thisapp#'
</cfquery>

Now understand that I don't use session variables at all in my apps and
never will. this is just a rough idea of what you would most likely do to
mimic client variables with session variables. Personally i would rewrite
the app to use client variables. But each to their own. You will probably
need to correct / rewrite some of this code. Hey I wrote it off a whime and
without testing :P.

dude all you have to do is make sure that each app has it's own application
name in the cfapplication tag.
name of app1
<cfapplication name="test">
name of app2
<cfapplication name="test2">
now the user's can't share session variables.

Subject: storing session variables in DB
I have a set of mirrored servers that are running off 1 SQL_server.
I have to recode the apps that use session variables because
a user could jump to a different server during a session. Is
there a simple way to fix this? Can 2 different servers be aware
of the same session? Can I store the session variables in the
SQL-server DB?
I am running Win2k, SQL-Server 2000, and (I know) CF%.0 Professional.
There is no need to tell me that the Enterprise version will
allow me to isolate a user to one server during a session.
Thanks in advance,
BJ
