Package: apt-proxy
Version: 1.9.35
Severity: normal

Hi

If apt-proxy is already downloading a file when another client requests the 
same file I get the exception below.  The client aptitude instance reports 
"[ERROR] Connection failed".

Needless to say this is an issue for when attempting to update multiple 
similar machines at the same time.

I believe that with pipelining enabled, the same situation seems to result in 
the same file being queued for download multiple times.  Hence I have 
disable_pipelining=1 in apt-proxy-v2.conf.

Since avoiding multiple download is the prime reason for using apt-proxy, 
perhaps pipelining should be disabled by default for etch?

Thanks for your work on Debian.

Andrew V.
