There is two ways you can do this

a) If the query parameter is irrelevant then use an url rewriter to
remove the query parameter from the URL (www.foo.com/test), or rewrite
it to a single value (www.foo.com/test?q=1 even if q=X was requested)

b) Alternatively you can use the store url rewriter capability found in
Squid-2.7 which allows you to teach Squid that the URLs are in fact one
and the same even if different, without rewriting the URL as such..

I would guess 'a' is the best match. 'b' is more intended for mitigating
the cache busting effect of distributed CDN networks where the same
content is found on a zillion different hosts with a easily identified
pattern...
