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...

		// cache the RSS feed if comments are enabled
		if ($this->ProvideComments) {
			$urls[] = Director::absoluteBaseURL() . "pagecomment/rss/" . $this->ID;
		}

...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

You can statically cache pagination (by augmenting the subPagesToCache() function). You could get comments working by adding a cache rebuild trigger on an extension to Comments, onAfterWrite but for the majority of sites partial caching might be suitable effort.
