Sorry, this is still wrong. HTTP/1.0 has a pipelining extension that
cannot really be detected.

This is 100% the fault of your server. There is no generic way to fix
software that does not implement the spec!

Yes, this is there specifically for this case.

This only says that the server can operate correctly in a non-pipelined
environment. Clearly it breaks when you begin to pipeline. I've seen it
before, they do something defective and it just breaks like this.
The specs basically require the server to support what APT does [without
corrupting files!], it is an RFC violation if it does not work.
What are you using for a server?
