Default page or not, Squid does not mind. All it needs is an Expires:
header at least a few seconds in the future.

Personally, I use a script which detects and sets teh header if its an
unknown URL (5 seconds caching, the client could be about to create it)
or one of the permanently dead ones (1 year caching with sometimes info
saying where the new one is).

How you do it depends on the server capabilities and website needs.
