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 hostnames
       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  hostnames,  even
       if there is an environment variable set for it.

       Enter IPv6 numerical addresses in the list of hostnames 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.

DEFAULT

       NULL

PROTOCOLS

       This functionality affects all supported protocols

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           /* accept various URLs */
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           /* 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);
         }
       }

AVAILABILITY

       Added in curl 7.19.4

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.
