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 zero 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"

       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
       CURLOPT_NOPROXY(3) option is not set. It works exactly the same way.

DEFAULT

       NULL

         /* 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);
       }
