  As noted, can you revise the server so it returns cacheable data? One
possibly simple way to do this (not necessarily the best) might be to
have the query generate a redirect to a static URL (e.g.
http://squid/temporary/db1000/123456.pdf) which should then be cached
by default.

  Another would be to have the query response return headers indicating
the data is cacheable and when it expires. A combination of the two
might be the best.

  As pointed out, this is going to end up messing up caching of every
other CGI and query URL accessed by users of your cache, and will still
not solve the problem for anybody accessing this server or database via
a different cache.
