Re: An API to search public repositories

Hi Evgeny,

When Artifactory contacts a remote repository it first sends a HEAD request
to see whether the artifact exists and if it has changed (changes are only
checked  for snapshots - the maven metadata is queried). Even though there
are more powerful search APIs provided by repo managers, including
Artifactory itself, this is the fastest direct query form, which is standard
and works with 'dumb' HTTP repositories as well (in fact, HTTP also offers
conditional-GET in a single request, but repo1 does not support it, so we
use a HEAD then GET). Other than that, each remore repository has an
expiring cache for snapshots, a cache for failed retrievals (network errors
etc.) and a cache for non-found artifacts (all configurable from the remote
repo advanced configuration panel).
The actual resolution order between repositories is explained here:
http://wiki.jfrog.org/confluence/display/RTF/Understanding+Repositories (the
last section called "Resolution Order").

HTH,

Yoav
