I have never tried anything along those lines but you could decorate a component and keep the rendered html in that decoration. Something along:

renderContentOn: html
	^ html html: (generatedHtml ifNil:[ generatedHtml := WAHtmlCanvas builder render:[:html2 | self renderNextOn: html2 ] ])

Though I’m seriously doubting any advantage in performance here by caching. This will only provide an advantage if the rendering code inside that cached component is slow.
If you need a page that is cached, try using a restful url in your app and turn on a front-end webserver page cache for that url.

Disclaimer: I also don’t know if the above really works and what caveats might arise. Keep us posted if you give it a try.
