Some questions and thoughts ...
It's obvious that using the cache approach, this mod would cause a duplication of attachments, which isn't a problem for people with large hard disk space available.
However, what I was wondering was, is there an impact on performance that would slow down the forums with the mod having to intercept every attachment being viewed by the user, then save it to the cache, then retrieve it again?
Thanks for any feedback ..
Regards,
Doug
