My client would then compute hash and store the results. Since I would make just one query for every cached url, I was assuming that the additional load might be less. Is there any other efficient way to achieve what I want to do?

I think you should contact Alex, (rousskov at measurement-factory.com)
about the MD5 hashing. He has been working on a project to calculate and
exchange object Digests for URL de-duplication on slow network links. It
also requires this type of hash calculation and AFAIK he has already
worked out how to do this efficiently inside Squid.
