Bug#523795: apt: chokes on "proxy-connection: keep-alive" header from transparent proxy

[Simon Richter <sjr@debian.org>]

Package: apt
Version: 0.7.20.2
Severity: normal

Hi,

if the network one is connected to uses a transparent proxy that adds 
this header line, apt fails to download Packages files. Manually 
configuring the proxy works fine.
