[IVY-1255] Possible bug in Ivy's maven resolver is causing massive amounts of redundant traffic

Description

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.
