* instead of making (dis)-allow 0.9 a property of connection info, work off a state machine that engages in the liberal skipping of junk before response headers only immediately after a no-content response on the same connection. * when scanning for response headers in a large amount of junk place a non infinite limit on that (128KB).. the only known use case for this is skipping illegal message bodies in 304's and those just aren't that big. --HG-- extra : rebase_source : 433fd6aae237d29a9957b1a70cf1e756af5a8af0
