If almost any page can have comments, then static cacheing can't be used useless there's a way to cache the comments too.

How can a page be automatically recached when a new comment is submitted?

In the example code here http://doc.silverstripe.org/sapphire/en/reference/staticpublisher, the subPagesToCache function checks for comments to cache the rss feed...

...so it looks like the author has considered the issue of comments, but there's no indication of how to show them.

Any ideas? What about dealing with comment form submissions, spam protection mesages etc. Surely someone has already worked all this out? What about using static cacheing with the Blog module e.g. paged results, widgets etc. Has that been tried successfully, or is it not worth it & better to stick with partial cacheing?

Thanks, Jules
