CURLOPT_NOPROXY(3) libcurl CURLOPT_NOPROXY(3)
NAME
CURLOPT_NOPROXY - disable proxy use for specific hosts
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOPROXY, char *noproxy);
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 noproxy 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.
Environment variables
If there is an environment variable called no_proxy (or NO_PROXY), it
is used if the CURLOPT_NOPROXY(3) option is not set. It works exactly
the same way.
