Change path's for images due to seperate users?

I have a issue.. I need to set the path for images, uploads, files etc. dynamically without beeing locked by the setup defaults.
I know I change the path's using the session object e.g.
"strSaveFileFolderPath = "<%session("username")%>\my_documents\my_files""

But this does not solve issuses regarding multiple user groups and different users using different interfaces..

Is there a way around to set specific paths in the asp-code when setting the textaera?

Please help me :)

The correct ASP syntax for your example should be:

strSaveFileFolderPath = session("username") & "\my_documents\my_files"
