Returning stale objects to neighbours?

Hello Squid users,

I'm using squid 1.1b19 in two machines (Linux 2.0.23). They are neighbours
of each other. Call them squid1 and squid2. There is a stale copy of the
object index2.html in squid1. When I access squid2 for this object, squid2
will ask squid1 for it and get a UDP_HIT_OBJ, which is a stale copy (with a
Last-Modified header of 10 days ago). When I access squid1 for the object
directly, it will TCP_REFRESH_MISS and fetch a fresh copy from the parent.
 The two squids use the same refresh_pattern in squid.conf. Any ideas?
 Thanks.
