             Summary: Extend "smart checksum" feature of resolver
                 Key: MRESOLVER-231
                 URL: https://issues.apache.org/jira/browse/MRESOLVER-231
             Project: Maven Resolver
          Issue Type: Task
          Components: Resolver
            Reporter: Tamás Cservenák


So far only Sonatype Nexus2 was supported (by http-transport).

This feature cuts back one extra HTTP roundtrip (to get sha1/md5), if they are 
already sent by upstream repository. And not only Nexus2 sends them. 
Effectively, if X artifacts are requested, this potentially halves HTTP request 
count (as X and X.hash is being request currently).
