As your dump showed in the other mail, the server is *NOT* at all sending the
data using chunked encoding. It's a bloody liar! ;-)

Right. I acknowledge your problem here.

I'm not quite sure what the best solution would be.

I mean, we could possibly come up with a way where you can filter out a given
header before libcurl parses it. That would solve this particular case, but I
doubt that you want to do that as a generic solution as that would
effectively prevent all the normal and functioning chunked downloads to

Another approach would be that libcurl, in a case where it finds a problem
with the chunked data somehow allows you to take care of it anyway, even
though it was not using correct syntax.

A third possibility, is that if the very first byte of the chunked-transfer
is found to be illegal (as in this case), we switch it off and get it all
(and the rest of this transfer) without using chunked transfer...

That server sure isn't playing very nice.
