caused the second call to fail.
sites in cases where the cookie clearly has a very old expiry date. The
condition was simply that libcurl's date parser would fail to convert the

missed date due to an unsupported date format or date range will now cause
the cookie to not match.
CURLOPT_POST301 (but adds a define for backwards compatibility for you who
don't define CURL_NO_OLDIES). This option allows you to now also change the
libcurl behavior for a HTTP response 302 after a POST to not use GET in the
subsequent request (when CURLOPT_FOLLOWLOCATION is enabled). I edited the
patch somewhat before commit. The curl tool got a matching --post302
option. Test case 1076 was added to verify this.
enabling this feature with CURLOPT_CERTINFO for a request using SSL (HTTPS
or FTPS), libcurl will gather lots of server certificate info and that info
can then get extracted by a client after the request has completed with
curl_easy_getinfo()'s CURLINFO_CERTINFO option. Linus Nielsen Feltzing
helped me test and smoothen out this feature.
Unfortunately, this feature currently only works with libcurl built to use
OpenSSL.

greatly simplified the generic layer in readability by involving much less
#ifdefs and other preprocessor stuff and should make it easier for people to
make libcurl work with new SSL libraries.
Hopefully I can later on document these 16 functions somewhat as well.

we had multiple states for which the internal function returned no socket at
all to wait for, with the effect that libcurl calls the socket callback (when
curl_multi_socket() is used) with REMOVE prematurely (as it would be added
again within very shortly)
handler functions didn't return that the socket should be waited for writing,
but instead it was treated as if no socket was needing monitoring so REMOVE
was called prematurely

The problem was that when libcurl rewound a stream meant for upload when it

closes the connection after that initial informational response.
libcurl would not properly re-initialize the connection to the proxy and

now detect if one or more authentication methods were available and asked
for, and will thus retry the connection and continue from there.

Also, the unused char *urlpath member is removed from struct FTP.
#2 - provide a Curl_reset_reqproto() function that frees
