1353	*
1354	*
1355	*
1356	* CURLOPT_HEADEROPT
1357	*
1358	* How to deal with headers. One of the following constants:
1359	*
1360	* CURLHEADER_UNIFIED: the headers specified in
1361	* CURLOPT_HTTPHEADER will be used in requests
1362	* both to servers and proxies. With this option enabled,
1363	* CURLOPT_PROXYHEADER will not have any effect.
1364	*
1365	*
1366	* CURLHEADER_SEPARATE: makes
1367	* CURLOPT_HTTPHEADER headers only get sent to
1368	* a server and not to a proxy. Proxy headers must be set with
1369	* CURLOPT_PROXYHEADER to get used. Note that if
1370	* a non-CONNECT request is sent to a proxy, libcurl will send both
1371	* server headers and proxy headers. When doing CONNECT, libcurl will
1372	* send CURLOPT_PROXYHEADER headers only to the
1373	* proxy and then CURLOPT_HTTPHEADER headers
1374	* only to the server.

1499	*
1500	*
1501	* CURLOPT_PROTOCOLS
1502	*
1503	*
1504	* Bitmask of CURLPROTO_* values. If used, this bitmask
1505	* limits what protocols libcurl may use in the transfer. This allows you to have
1506	* a libcurl built to support a wide range of protocols but still limit specific
1507	* transfers to only be allowed to use a subset of them. By default libcurl will
1508	* accept all protocols it supports.
1509	* See also CURLOPT_REDIR_PROTOCOLS.

1566	*
1567	*
1568	* CURLOPT_REDIR_PROTOCOLS
1569	*
1570	* Bitmask of CURLPROTO_* values. If used, this bitmask
1571	* limits what protocols libcurl may use in a transfer that it follows to in
1572	* a redirect when CURLOPT_FOLLOWLOCATION is enabled.
1573	* This allows you to limit specific transfers to only be allowed to use a subset
1574	* of protocols in redirections. By default libcurl will allow all protocols
1575	* except for FILE and SCP. This is a difference compared to pre-7.19.4 versions
1576	* which unconditionally would follow to all protocols supported.
1577	* See also CURLOPT_PROTOCOLS for protocol constant values.
1578	*
1579	*

1642	* CURLOPT_SSL_VERIFYHOST
1643	*
1644	* 1 to check the existence of a common name in the
1645	* SSL peer certificate. 2 to check the existence of
1646	* a common name and also verify that it matches the hostname
1647	* provided. 0 to not check the names. In production environments the value of this option

1797	* CURLOPT_TIMEVALUE. If it hasn't been modified,
1798	* a "304 Not Modified" header will be returned
1799	* assuming CURLOPT_HEADER is TRUE.
1800	* Use CURL_TIMECOND_IFUNMODSINCE for the reverse

1889	*
1890	*
1891	* CURLOPT_IPRESOLVE
1892	*
1893	* Allows an application to select what kind of IP addresses to use when
1894	* resolving host names. This is only interesting when using host names that
1895	* resolve addresses using more than one version of IP, possible values are
1896	* CURL_IPRESOLVE_WHATEVER,
1897	* CURL_IPRESOLVE_V4,
1898	* CURL_IPRESOLVE_V6, by default

1919	*
1920	*
1921	* This option is deprecated, as it was never implemented in cURL and
1922	* never had any effect.
1923	*
1924	* The HTTP authentication method(s) to use. The options are:
1925	* CURLAUTH_BASIC,
1926	* CURLAUTH_DIGEST,
1927	* CURLAUTH_GSSNEGOTIATE,
1928	* CURLAUTH_NTLM,
1929	* CURLAUTH_ANY, and
1930	* CURLAUTH_ANYSAFE.
1931	*
1932	* The bitwise \| (or) operator can be used to combine
1933	* more than one method. If this is done, cURL will poll the server to see
1934	* what methods it supports and pick the best one.
1935	*
1936	* CURLAUTH_ANY is an alias for
1937	* CURLAUTH_BASIC \| CURLAUTH_DIGEST \| CURLAUTH_GSSNEGOTIATE \| CURLAUTH_NTLM.
1938	*
1939	* CURLAUTH_ANYSAFE is an alias for
1940	* CURLAUTH_DIGEST \| CURLAUTH_GSSNEGOTIATE \| CURLAUTH_NTLM.
1941	*
1942	* Bitmask of CURLPROTO_* values. If used, this bitmask
1943	* limits what protocols libcurl may use in the transfer. This allows you to have
1944	* a libcurl built to support a wide range of protocols but still limit specific
1945	* transfers to only be allowed to use a subset of them. By default libcurl will
1946	* accept all protocols it supports.
1947	* See also CURLOPT_REDIR_PROTOCOLS.
1948	*
1949	* Valid protocol options are:
1950	* CURLPROTO_HTTP,

1967	* CURLAUTH_NONE.
1968	*
1969	* The bitwise \| (or) operator can be used to combine
1970	* more than one method. If this is done, cURL will poll the server to see
1971	* what methods it supports and pick the best one.
1972	*
1973	* CURLAUTH_BASIC allows username/password authentication.
1974	*
1975	* CURLAUTH_GSSAPI allows GSS-API authentication.
1976	*
1977	* CURLAUTH_NONE allows no authentication.
1978	*
1979	* Defaults to CURLAUTH_BASIC\|CURLAUTH_GSSAPI.
1980	* Set the actual username and password with the CURLOPT_PROXYUSERPWD option.
1981	*
1982	* Your best bet is to not set this and let it use the default.
1983	* Setting it to 2 or 3 is very dangerous given the known
1984	* vulnerabilities in SSLv2 and SSLv3.
1985	*
1986	* Your best bet is to not set this and let it use the default CURL_SSLVERSION_DEFAULT
1987	* which will attempt to figure out the remote SSL protocol version.
1988	*
1989	* value should be a string for the
1990	* following values of the option parameter:

2002	* CURLOPT_ABSTRACT_UNIX_SOCKET
2003	*
2004	* Enables the use of an abstract Unix domain socket instead of
2005	* establishing a TCP connection to a host and sets the path to
2006	* the given string. This option shares the same semantics
2007	* as CURLOPT_UNIX_SOCKET_PATH. These two options
2008	* share the same storage and therefore only one of them can be set
2009	* per handle.

2069	*
2070	* A cookie string (i.e. a single line in Netscape/Mozilla format, or a regular

2072	* "ALL" erases all cookies held in memory.
2073	* "SESS" erases all session cookies held in memory.
