CURLOPT_PROXY_SSL_CIPHER_LIST(3)			     curl_easy_setopt options				  CURLOPT_PROXY_SSL_CIPHER_LIST(3)

NAME

       CURLOPT_PROXY_SSL_CIPHER_LIST - specify ciphers to use for proxy TLS

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSL_CIPHER_LIST, char *list);

DESCRIPTION

       Pass a char *, pointing to a zero terminated string holding the list of ciphers to use for the connection to the HTTPS proxy. The list must
       be syntactically correct, it consists of one or more cipher strings separated by colons. Commas or spaces are  also  acceptable	separators
       but colons are normally used, !, - and + can be used as operators.

       For  OpenSSL  and  GnuTLS valid examples of cipher lists include 'RC4-SHA', 'SHA1+DES', 'TLSv1' and 'DEFAULT'. The default list is normally
       set when you compile OpenSSL.

       You'll find more details about cipher lists on this URL:

	https://www.openssl.org/docs/apps/ciphers.html

       For NSS, valid examples of cipher lists include 'rsa_rc4_128_md5', 'rsa_aes_128_sha', etc. With NSS you don't add/remove  ciphers.  If  one
       uses this option then all known ciphers are disabled and only those passed in are enabled.

       You'll find more details about the NSS cipher lists on this URL:

	http://git.fedorahosted.org/cgit/mod_nss.git/plain/docs/mod_nss.html#Directives

       The application does not have to keep the string around after setting this option.

DEFAULT

       NULL, use internal default

PROTOCOLS

       All

EXAMPLE

       TODO

AVAILABILITY

       Added in 7.52.0

       If built TLS enabled.

RETURN VALUE

       Returns CURLE_OK if TLS is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.

CURLOPT_PROXY(3)					     curl_easy_setopt options						  CURLOPT_PROXY(3)

NAME

       CURLOPT_PROXY - set proxy to use

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY, char *proxy);

DESCRIPTION

       Set the proxy to use for the upcoming request. The parameter should be a char * to a zero terminated string holding the host name or dotted
       numerical IP address. A numerical IPv6 address must be written within [brackets].

       To specify port number in this string, append :[port] to the end of the host name. The proxy's port number may optionally be specified with
       the separate option CURLOPT_PROXYPORT(3). If not specified, libcurl will default to using port 1080 for proxies.

       The proxy string may be prefixed with [scheme]:// to specify which kind of proxy is used.

	      http://
		     HTTP Proxy. Default when no scheme or proxy type is specified.

	      https://
		     HTTPS Proxy. (Added in 7.52.0 for OpenSSL, GnuTLS and NSS)

	      socks4://
		     SOCKS4 Proxy.

	      socks4a://
		     SOCKS4a Proxy. Proxy resolves URL hostname.

	      socks5://
		     SOCKS5 Proxy.

	      socks5h://
		     SOCKS5 Proxy. Proxy resolves URL hostname.

       Without a scheme prefix, CURLOPT_PROXYTYPE(3) can be used to specify which kind of proxy the string identifies.

       When  you  tell	the library to use a HTTP proxy, libcurl will transparently convert operations to HTTP even if you specify an FTP URL etc.
       This may have an impact on what other features of the library you can use, such as CURLOPT_QUOTE(3) and similar FTP  specifics  that  don't
       work unless you tunnel through the HTTP proxy. Such tunneling is activated with CURLOPT_HTTPPROXYTUNNEL(3).

       libcurl	respects the environment variables http_proxy, ftp_proxy, all_proxy etc, if any of those are set. The CURLOPT_PROXY(3) option does
       however override any possibly set environment variables.

       Setting the proxy string to "" (an empty string) will explicitly disable the use of a proxy, even if there is an environment  variable  set
       for it.

       A proxy host string can also include protocol scheme (http://) and embedded user + password.

       The application does not have to keep the string around after setting this option.

DEFAULT

       Default is NULL, meaning no proxy is used.

       When you set a host name to use, do not assume that there's any particular single port number used widely for proxies. Specify it!

PROTOCOLS

       All except file://. Note that some protocols don't do very well over proxy.

EXAMPLE

       TODO

AVAILABILITY

       Since 7.14.1 the proxy environment variable names can include the protocol scheme.

       Since 7.21.7 the proxy string supports the socks protocols as "schemes".

       Since 7.50.2, unsupported schemes in proxy strings cause libcurl to return error.

RETURN VALUE

       Returns CURLE_OK if proxies are supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
