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 do not 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
       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);
       }
