------------------------------------

Do you also have any information regarding the configuration of the Ivy clients?

>          Issue Type: Bug
>          Components: Maven Compatibility
>    Affects Versions: 2.1.0

> 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.
