Looping weirdness.

Hi,

I've got two caches here A and B. A is the 'main' cache witch gets all the
users requestes. B is a 'helper' cache for A.

A requests cache-digests from B. The strange thing is when A requsts a
cache-digest from B I get:

1999/06/10 14:44:47| WARNING: Forwarding loop detected for:
GET /squid-internal-periodic/store_digest HTTP/1.0
If-Modified-Since: Thu, 10 Jun 1999 11:39:47 GMT
Accept: application/cache-digest
Accept: text/html
Host: cacheB:800
Via: 0.0 cacheA:800 (Squid/2.2.STABLE3), 1.0 cacheB:800 (Squid/2.2.STABLE3)
X-Forwarded-For: unknown, cacheA
Cache-Control: max-age=1209600
Connection: keep-alive

on the B machine.

So according to the docs the last host in the Via: list is the host witch
forwarded the request. So cache B is forwaring the request to it's self?!?!
How is this ever possible?

I know I can prevent this by using acl's and stuff, but it seems more like
a bug to me. Isn't it completely useless to forward a request to yourself?
Should digests be forwarded anyway?

cacheA has cacheB configured as a parent, cacheB A as a sibling.

Thanks for any thoughts.

alex.
