path : string

  This extracts the request's URL path, which starts at the first slash and

  ends before the question mark (without the host part). A typical use is with

  prefetch-capable caches, and with portals which need to aggregate multiple

  information from databases and keep them in caches. Note that with outgoing

  caches, it would be wiser to use "url" instead. With ACLs, it's typically

  used to match exact file names (eg: "/login.php"), or directory parts using

  the derivative forms. See also the "url" and "base" fetch methods.
