This is where AJAX and Web2.0 stuff actually has some use. A static
long-term cacheable page with known IDs spread around as needed.
Combined with ajax calls that load some things to fill the HTML
containers with.

NP: the only relation this has to squid is which objects are cacheable,
for how long and which are not. You get to decide on all that by
yourself though.

An alternative that has a lot more to do with Squid is ESI. Which Squid
caches the templates and various bits with their own caching times and
generates the final client pages as requested.
  ESI in Squid has a few known bugs which prevent the more complex stuff
from working. But for simple uses like you ask it's happy and working in
some large production sites.
