The law school portal, which people log into, creates a session variable of
the unique id which allows them to have the site custom to them. I have
developed a module with its own Application.cfm and would like to pass that
session variable to the new application. Can this be done without renaming
the new module the same application name as the main portal.

I don't think that would work. Sessions are tied to the application that spawn them.

<cfapplication name="app1" sessionmanagement="true">
<cfset session.app1 = "app1">


<cfapplication name="app2" sessionmanagement="true">
<cfset session.app2 = "app2">


<cfset variables.transfer = structNew()>

<cfapplication name="app1" sessionmanagement="true">
<cfset structAppend(variables.transfer, session)>

<cfapplication name="app2" sessionmanagement="true">
<cfset structAppend(variables.transfer, session)>

<cfapplication name="app3" sessionmanagement="true">

<cfset session.app3 = "app3">

<cfset session.transfer = variables.transfer>

<cfdump var="#session#">

It's not hard to transfer session variables from one app to another
(obviously provided they're on the same CF instance).

To do it between CF instances, it's not hard to do it with a web service or
a <cfhttp> call or something like that.

Adam,

Once you have the session variables transferred to the new application, how do
you reference them? Can you just use session.variablename or do you need to do
session.app.variablename? I've done my cfdump and I see the varaibles but I
can't seem to get to the values.

Thanks
