title: Why npm packages stored via Artifactory have '-' (dash) in their path?
body: <p>After setting up a remote repository for NPM and having successfully retrieved the dependencies via Artifactory, I saw that all NPM packages are stored with an intermediate dash '-' in their path, such as :</p>
  
  <p><a href="http://host:8081/artifactory/npm-remote-cache/abbrev/-/abbrev-1.0.7.tgz" rel="noreferrer">http://host:8081/artifactory/npm-remote-cache/abbrev/-/abbrev-1.0.7.tgz</a></p>
  
  <p>It's also the same for the published version to a local npm repository.
  Both repositories are using the npm-default layout.</p>
  
  <p>No big deal there, but does anyone know why is this dash here in the middle ?</p>
  
  <p>Thanks in advance !</p>
