CURLOPT_NOPROXY(3)         curl_easy_setopt options         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, 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.

Environment variables
       If there's an environment variable called no_proxy (or NO_PROXY), it
       will be used if the _NOPROXY&section=3">CURLOPT_NOPROXY(3) option is not set. It works
       exactly the same way.

DEFAULT
       NULL

PROTOCOLS
       Most

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         /* accept various URLs */
         curl_easy_setopt(curl, CURLOPT_URL, input);
         /* use this proxy */
         curl_easy_setopt(curl, CURLOPT_PROXY, "http://proxy:80");
         /* ... but make sure this host name is not proxied */
         curl_easy_setopt(curl, CURLOPT_NOPROXY, "www.example.com");
         curl_easy_perform(curl);
       }
