Package dk.netarkivet.viewerproxy

This module gives access to previously harvested material, through a proxy solution.

• The viewerproxy component supports transparent access to the harvested data, using a proxy solution, and an archive with an index over URLs stored in the archive.
• Support for browsing an entire crawl (like a snapshot or event harvest) or a single job (what one machine harvested).
• Allows for collecting unharvested URLs while browsing, for use in curation, and to include these URLs in the next crawl.
