It is more about HTTP proxying and it is my understanding that response to CONNECT method request has that empty line after the successful (2xx) response line and zero or more response headers. The code is still wrong; it does not have a loop to discard the potential response headers that come before the empty line the code we are discussing discards. By the way does anybody know where this behaviour is officially specified? Luotonen's draft-luotonen-web-proxy-tunneling-01.txt is pretty clear about the empty line that comes after the response headers, but that document being an internet-draft has expired long time ago, but still seem to be quoted by others. >> The "I/O Operators" section talks about evaluating <$s> in a >> scalar context (i.e. "$rep = <$s>"), which we all know would >> return a single line, and in list context, which swallows > > This is in scalar context, and that's safe to rely on. If it were in scalar context I would agree fully. That behaviour is documented. But my point is that it is in void context, and I did not find document specifying what should happen. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
