If nothing else, I guess this will teach you to test run recent libcurls more
often and carefully! :-O After all, this change was done in november last
year without much complaints or anything.

The way I read RFC2616, that kind of reply is not a legal HTTP response. I
understand this is not what you're saying, but are you saying I do the wrong

It works just fine for you, sure since that was how libcurl did it before. The
problem for me is that it isn't then following the RFC and thus libcurl
doesn't behave properly when a "legal" HTTP response comes with no such

I would instead suggest that we work on a fix that detects HTTP version or
something, and do this check based on that since I'm referring to the HTTP 1.1
spec and your streams don't seem to adhere to that? Aren't you even using
HTTP200ALIASES to match the response?

I can't think of any work-around that doesn't involve changing the server,
using a proxy or patching the source code, no.
