This patch is part of the patchset I'm using in the Debian squid-2.4.3
package. Though the patches here are against 2.4.3, they should apply
to 2.5 with minor difficulty.

icp_hit_stale.patch Don't return 504 on cache-only requests for
                        stale objects if icp_hit_stale is on.

  Subject: squid: [PATCH] Make icp_hit_stale useful again
  To: submit@bugs.debian.org
  X-Mailer: bug 3.3.4
  Delivered-To: submit@bugs.debian.org

  Package: squid
  Version: 2.2.5-3
  Severity: normal

  Recent versions of squid will return 504 when a client makes a cache-only
  request and the object happens to be stale.

  This effectively makes icp_hit_stale because in that case the object is
  almost guaranteed to be stale and if the client is a sibling squid, it will
  always be cache-only.

  The follow patch addresses this by check for icp_hit_stale in this case.
