ESI (supported by Varnish and Akamai and with a slightly different syntax by nginx) allows for HTML tag-like commands in the page source like
<esi:include src="http://example.com/ssi.php?key=abcd" > so that the static parts of the page is cached in (for example) Varnish and only the dynamic bits are fetched dynamically. ssi.php is a very small program that connects to, say, memcached reads the value of the specified key and prints it (this esi.php is completely David Strauss' idea). Now, if Drupal would be able to serve page templates and cache the dynamic pieces into memcached then we could scale through the roof. And we are close... patch to follow I just wanted to file the issue so I can link to it from the code comment.
