A Content Addressable Storage (CAS) allows stored information to be retrieved based on its content, not on its location.



  • Fixed content files or documents need to be accessed by the content that they hold, even when the searcher cannot be expected to know exactly where the content is stored.
  • While this could be solved by modern search engines, the location of the content may move or be utterly irrelevant.
  • As a general rule the content is not expect to change often, or perhaps never change at all, so that the content is a good basis for finding it.
