Then you should get a « 502 Server dropped connection » error. If you
don't, please report it as a bug.

This shouldn't happen -- unless Polipo's immediate upstream happens to
be an HTTP/1.0 implementation. (Even if the upstream is HTTP/1.0,
this should only happen if the upstream sends no Content-Length *and*
the connection is broken just after the CR-LF-CR-LF that ends the
Please let me state this once more. HTTP/1.0 is obsolete, it is slow,
it is unreliable. I've done my best to make HTTP/1.0 reasonably
reliable in Polipo, but there's really not much that one can hack
around with such a deficient protocol.
(Note that, since HTTP/1.1 is backwards compatible with 1.0, it is
possible to send an HTTP/1.0 reply with an HTTP/1.1 header.)

Then don't do that. Privoxy is downgrading perfectly good HTTP/1.1
replies down to the old, unreliable, HTTP/1.0 kind. (Note that it
does tag them with « HTTP/1.1 », which it is perfectly allowed to do.)
Tested with Privoxy 3.0.6.

Yes, there's a special hack to ensure that objects served as HTTP/1.0
are less sticky than normal. (File server.c line 2086.)
