Looking at the curl_proxytype enum, I am nearly convinced that this is
the correct place this after all, as it seems more consistent with how
the SOCKS proxies are done. I am a fan of consistency... There are a
couple of options here, though, and I would like some opinions. I am
currently thinking of adding:
CURLPROXY_HTTP_1_0 = 1,
CURL_PROXY_HTTP_1_1 = 2,
and having CURLPROXY_HTTP act somewhat like the current
CURL_HTTP_VERSION_NONE, and try to determine for itself what to use.
The alternative would be just to add CURL_PROXY_HTTP_1_1 = 1, and have
it default to 1_0. This option has the advantage of preserving current
functionality, which apparently hasn't broken for very many people. I
have investigated our set-up here, and it appears that this is
breaking when doing https: authentication through a Microsoft ISA web
The reaon I would prefer to have it use 1.1 if possible as a default
is that it appears to be more standards-compliant that way...
