Figuring out which is which is a non-trivial task for your image serving URL. If you really, really don't like the SessionVar idea, you can bind a function to your /image request and that function can deposit a reference to the current stateful snippet into a RequestVar that can be accessed during the image serving process. If you like that answer better, give me a few days to whip up an example. > > Thanks for the advice. > > -Ross > > On Jul 13, 2009, at 6:38 PM, David Pollak wrote: > > > > On Mon, Jul 13, 2009 at 3:21 PM, Ross Mellgren <[email protected]> wrote: > >> >> Hi all, >> >> Is there any way to get a StatefulSnippet instance for a particular >> class in the current session?
