Re: Custom Directive Arguments?

[Gabriel Sidler <si...@teamup.ch>]

Rick,
I'd really like to see some caching support in Velocity. This would
be a very valuable add-on.
My approach in the past has been to cache in the model instead of in the
view. But, for many application cases this is really a pain. It makes the
interface between model and view more complicated than necessary and
introduces unnessessary dependencies. My experience is that caching of
complex view snippets can lead to impressive performance improvements.

I'd just like to encourage you to push on with this and share your results
with the community.
