 * - canonical URL path: path component of the URL: this is used to reconstruct URLs to resources and is not adjusted by
 * DFS referrals. (E.g. a resource with a DFS root's parent will still point to the DFS root not the share it's actually
 * located in).
 * - share + uncpath within it: This is the relevant information for most SMB requests. Both are adjusted by DFS
