Package: apt Version: 0.5.14 Severity: minor Apt-get update uses HTTP/1.1 pipeling by default, which is pretty good. However, it doesn't check whether the server supports pipelining, which breaks certain proxies (notably WWWOFFLE and Junkbuster).
In order to reproduce that, run ``nc -l -p 1234'' in one window, and ``http_proxy=http://localhost:1234 apt-get update'' in another. You'll see a bunch of requests straight away, which is incorrect in the case of an HTTP/1.0 proxy. The recommended approach (RFC 2616 8.1.2) is to do a single request first, and then start pipelining if the proxy or server gave an HTTP/1.1 (or later) persistent reply. Whether to pipeline when the server gave an HTTP/1.0 persistent reply is up to you, old Apache will work, but old IIS will break. Please do not disable pipelining altogether, as this would signi- ficantly slow apt-get down. Thanks, Juliusz Chroboczek
