Possible bug in Ivy's maven resolver is causing massive amounts of redundant traffic
------------------------------------------------------------------------------------

                 Key: IVY-1255
                 URL: https://issues.apache.org/jira/browse/IVY-1255
             Project: Ivy
          Issue Type: Bug
          Components: Maven Compatibility
    Affects Versions: 2.1.0
            Reporter: Brian Fox


We were investigating suspicious download trends of groovy as reported by the central statistics,
and I found some odd behavior from Ivy. I see from many ips massively repeated Head requests
spread across many groovy poms and in some cases repeated sequential hits on the same pom
milliseconds apart. The attached log shows the  behavior from one IP on one day in December.
Obviously this is all using the same version of Ivy,  but I did notice initially this occurring
from many versions.

Since Maven release artifacts never change, the HEAD request should never be needed, since
I assume the file is cached somewhere locally (or you would be doing a get). 

If you need more info from the logs, I'd be glad to help.
