.TH CURLOPT_NOPROXY 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_NOPROXY \- disable proxy use for specific hosts
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOPROXY, char *noproxy);
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a null-terminated string. The string consists of a comma
|
|
separated list of host names that do not require a proxy to get reached, even
|
|
if one is specified. The only wildcard available is a single * character,
|
|
which matches all hosts, and effectively disables the proxy. Each name in this
|
|
list is matched as either a domain which contains the hostname, or the
|
|
hostname itself. For example, example.com would match example.com,
|
|
example.com:80, and www.example.com, but not www.notanexample.com or
|
|
example.com.othertld.
|
|
|
|
If the name in the noproxy list has a leading period, it is a domain match
|
|
against the provided host name. This way ".example.com" will switch off proxy
|
|
use for both "www.example.com" as well as for "foo.example.com".
|
|
|
|
Setting the noproxy string to "" (an empty string) will explicitly enable the
|
|
proxy for all host names, even if there is an environment variable set for it.
|
|
|
|
Enter IPv6 numerical addresses in the list of host names without enclosing
|
|
brackets:
|
|
|
|
"example.com,::1,localhost"
|
|
|
|
IPv6 numerical addresses are compared as strings, so they will only match if
|
|
the representations are the same: "::1" is the same as "::0:1" but they don't
|
|
match.
|
|
|
|
The application does not have to keep the string around after setting this
|
|
option.
|
|
.SH "Environment variables"
|
|
If there's an environment variable called \fBno_proxy\fP (or \fBNO_PROXY\fP),
|
|
it will be used if the \fICURLOPT_NOPROXY(3)\fP option is not set. It works
|
|
exactly the same way.
