Yes.

Have the ASP file return proper Cache-Control headers, and NO no-cache
header. And do not use the recommended no_cache configuration blocking
caching of query URLs.

The basic caching algorithm in Squid does not care much about the URL,
only the response headers. The squid.conf directives no_cache and
refresh_pattern can be used to tune the caching algorithm based un URL
patterns.

However, Squid cannot cache pages marked as uncachable by the origin
server, irregardless of the URL format.
