Now, there are only 2.0.2 squids left. Digests are disabled (not compiled)
on any of those caches. But I will try and put the "no-digest" option
there in addition.

As I found out later (and wrote about), the forwarding loops hits with
documents which have the HTTP reply status "302 moved temporarily" or "304
moved permanently". The nuisance (it is not a problem, since the loops are
detected and broken, but latency is added) still occurs quite heavily.
