Libraries like smarty (PHP caching framework) do it this way :
fun render_and_cache_id (id)
let query_db_then_render = fun() -> build_html ( query_db ( id_of_thing .. ))
return cache(id, timeout, render_html)
endf
id is the id identifying the database data. Thus for each id the
database is queried only once - and the data is only rendered once.
Obviously this only works great if you have readonly data - or if its ok
if your data is out of date. You can invalidate it using timeouts etc.
