* HTTPS proxies:
An HTTPS proxy receives all transactions over an SSL/TLS connection.
Once a secure connection with the proxy is established, the user agent
uses the proxy as usual, including sending CONNECT requests to instruct
the proxy to establish a [usually secure] TCP tunnel with an origin
server. HTTPS proxies protect nearly all aspects of user-proxy
communications as opposed to HTTP proxies that receive all requests
(including CONNECT requests) in vulnerable clear text.
With HTTPS proxies, it is possible to have two concurrent _nested_
SSL/TLS sessions: the "outer" one between the user agent and the proxy
and the "inner" one between the user agent and the origin server
(through the proxy). This change adds supports for such nested sessions
as well.
A secure connection with a proxy requires its own set of the usual SSL
options (their actual descriptions differ and need polishing, see TODO):
--proxy-cacert FILE CA certificate to verify peer against
--proxy-capath DIR CA directory to verify peer against
--proxy-cert CERT[:PASSWD] Client certificate file and password
--proxy-cert-type TYPE Certificate file type (DER/PEM/ENG)
--proxy-ciphers LIST SSL ciphers to use
--proxy-crlfile FILE Get a CRL list in PEM format from the file
--proxy-insecure Allow connections to proxies with bad certs
--proxy-key KEY Private key file name
--proxy-key-type TYPE Private key file type (DER/PEM/ENG)
--proxy-pass PASS Pass phrase for the private key
--proxy-ssl-allow-beast Allow security flaw to improve interop
--proxy-sslv2 Use SSLv2
--proxy-sslv3 Use SSLv3
--proxy-tlsv1 Use TLSv1
--proxy-tlsuser USER TLS username
--proxy-tlspassword STRING TLS password
--proxy-tlsauthtype STRING TLS authentication type (default SRP)
All --proxy-foo options are independent from their --foo counterparts,
except --proxy-crlfile which defaults to --crlfile and --proxy-capath
which defaults to --capath.
Curl now also supports %{proxy_ssl_verify_result} --write-out variable,
similar to the existing %{ssl_verify_result} variable.
Supported backends: OpenSSL, GnuTLS, and NSS.
* A SOCKS proxy + HTTP/HTTPS proxy combination:
If both --socks* and --proxy options are given, Curl first connects to
the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS
proxy.
TODO: Update documentation for the new APIs and --proxy-* options.
Look for "Added in 7.XXX" marks.

.TH curl_easy_setopt 3 "25 Jun 2014" "libcurl 7.38.0" "libcurl Manual"
|
|
.SH NAME
|
|
curl_easy_setopt \- set options for a curl easy handle
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLoption option, parameter);
|
|
.SH DESCRIPTION
|
|
\fIcurl_easy_setopt(3)\fP is used to tell libcurl how to behave. By setting
|
|
the appropriate options, the application can change libcurl's behavior. All
|
|
options are set with an \fIoption\fP followed by a \fIparameter\fP. That
|
|
parameter can be a \fBlong\fP, a \fBfunction pointer\fP, an \fBobject
|
|
pointer\fP or a \fBcurl_off_t\fP, depending on what the specific option
|
|
expects. Read this manual carefully as bad input values may cause libcurl to
|
|
behave badly! You can only set one option in each function call. A typical
|
|
application uses many \fIcurl_easy_setopt(3)\fP calls in the setup phase.
|
|
|
|
Options set with this function call are valid for all forthcoming transfers
|
|
performed using this \fIhandle\fP. The options are not in any way reset
|
|
between transfers, so if you want subsequent transfers with different options,
|
|
you must change them between the transfers. You can optionally reset all
|
|
options back to internal default with \fIcurl_easy_reset(3)\fP.
|
|
|
|
Strings passed to libcurl as 'char *' arguments, are copied by the library;
|
|
thus the string storage associated to the pointer argument may be overwritten
|
|
after \fIcurl_easy_setopt(3)\fP returns. The only exception to this rule is
|
|
really \fICURLOPT_POSTFIELDS(3)\fP, but the alternative that copies the string
|
|
\fICURLOPT_COPYPOSTFIELDS(3)\fP has some usage characteristics you need to
|
|
read up on.
|
|
|
|
The order in which the options are set does not matter.
|
|
|
|
Before version 7.17.0, strings were not copied. Instead the user was forced
|
|
keep them available until libcurl no longer needed them.
|
|
|
|
The \fIhandle\fP is the return code from a \fIcurl_easy_init(3)\fP or
|
|
\fIcurl_easy_duphandle(3)\fP call.
