Doing this would also unobfuscate some of the code around coding/decoding this information through the Via header, which is pretty confusing. In particular, I think some of the logic around
{code}
void
HttpTransactHeaders::generate_and_set_squid_codes(HTTPHdr *header,
                                                 char *via_string,
                                                 HttpTransact::SquidLogInfo *squid_codes)
{code}

could get simplified, if we passed this information from the cache back through the HttpSM.

> This would be an incompatible change, so would go into v6 or v7 at the earliest. I'm marking it for Sometimes.
> The reason this is useful is going forward, we have multiple cache tiers. The Squid codes can track that, but the Via code only has RAM cache hit (or not).
> This is somewhat related to TS-3036.
