Cannot change UserFilePath (FileBrowse)

I am using ASP.Net and I have changed the variable "ConfigUserFilesPath" in FCKeditor/editor/filemanager/browser/default/connectors/asp/config.asp.
whichg works fine.

But Now I want to change it dyanamicaly (it depends on the person that is logged in which directory he may see).

Normally I would read a session id, but since the rest of the application is in ASP.Net (vb) and this is an ASP file I cannot get the variable.
I als cannot use config.aspx, since the code behind file is not shipped and problably not in VB if it was.

Can anybody please help (this is taking me days already)?

(if there would me a method /propertie of the ASP Object that would work as wellI gues there is not such one)

thx, Michael
