And FWIW I have experienced this problem for years too, but never figured out why until this discussion came up. And I do want to claim more than common user knowledge of http proxy servers. Still, it never occured to me that my spurious apt problems could be caused by proxies. And no, it's not just squid - I've been seeing the exact same at work where the office network have some intercepting proxy solution from websense. Anyway, this is definitely the type of problem that can and do exist for years without that necessarily causing a massive number of bug reports against apt. I still do not think that is an argument against fixing it? Can we please agree that in the real world 1) RFC1123 beats any other standard: "Be liberal in what you accept, and conservative in what you send", and 2) http proxy servers cannot always process pipelined requests due to the complexity this adds (complexity is always bad for security), and 3) http clients cannot know whether their requests are proxied ? The sum of these three points is that a http client should never send pipelined requests. Bjørn -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
