How to log flex -> cfc communication

Hi,

I am working on a Flex application using remote objects and CF8.

I have dozen of cfc's with few functions inside.

What I want to realize is to log (in a database) every function called with their passed arguments (from flex) and the userid.

for example here's the information I want to store :

is it possible to do without changing the flex application and only using coldfusion (application.cfc + events)

I am already able to retrieve current connected users.

using this script (the authentication is done in a cfm page then it redirects to the Flex app with the userid)  :

<cfparam name="application.sessionTracker" default="#StructNew()#"> <cfset objLog = {      userid = URL.value,      in = now(),      area = area } /> <cfset dummy = structInsert(      application.sessionTracker,      URL.value,      objLog, true)>

Here's the structure of the different directories :

- FTP root

     - my Flex app folder

          . application.cfm

          . index.cfm   

          . myapp.swf

          .myapp.html

     - cfc's folder

          - folder 1

               . file1.cfc

               . file2.cfc

...

I hope that my question is clear

Regards,

Aubry
