.TH CURLOPT_NOPROXY 3 "19 Jun 2014" libcurl libcurl
|
|
.SH NAME
|
|
CURLOPT_NOPROXY \- disable proxy use for specific hosts
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOPROXY, char *noproxy);
|
|
.fi
|
|
.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, "ample.com" would match ample.com, ample.com:80,
|
|
and www.ample.com, but not www.example.com or ample.com.org.
|
|
|
|
Setting the \fInoproxy\fP string to "" (an empty string) explicitly enables
|
|
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"
|
|
|
|
Since 7.86.0, IP addresses specified to this option can be provided using CIDR
|
|
notation: an appended slash and number specifies the number of "network bits"
|
|
out of the address to use in the comparison. For example "192.168.0.0/16"
|
|
would match all addresses starting with "192.168".
|
|
|
|
The application does not have to keep the string around after setting this
|
|
option.
|
|
.SH "Environment variables"
|
|
If there is an environment variable called \fBno_proxy\fP (or \fBNO_PROXY\fP),
|
|
it is used if the \fICURLOPT_NOPROXY(3)\fP option is not set. It works exactly
|
|
the same way.
|
|

|
