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) 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"

       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'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

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);
       }

RETURN VALUE

       Returns   CURLE_OK   if   the   option  is  supported,  CURLE_UNKNOWN_OPTION  if  not,  or
       CURLE_OUT_OF_MEMORY if there was insufficient heap space.
