p***p 发帖数: 559	1 I am writing a DNS cache, map domain name and transport to DNS entry in a Hashmap, both keys are string. I designed a key as a String=domain+transport , well, it is not so intelligent, any other idea?
m******t 发帖数: 2416	2 I would have done transport+domain, which is a lot more intelligent. No, I'm just kidding. What's wrong with domain+transport? In fact I can't think of any better way to guarantee uniqueness.
