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.
