     16 # NAME
     17 
     18 CURLOPT_NOPROXY - disable proxy use for specific hosts
     19 
     20 # SYNOPSIS
     21 
     22 ~~~c
     23 #include <curl/curl.h>
     24 
     25 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOPROXY, char *noproxy);
     26 ~~~
     27 
     28 # DESCRIPTION
     29 
     30 Pass a pointer to a null-terminated string. The string consists of a comma
     31 separated list of hostnames that do not require a proxy to get reached, even
     32 if one is specified. The only wildcard available is a single * character,
     33 which matches all hosts, and effectively disables the proxy. Each name in this
     34 list is matched as either a domain which contains the hostname, or the
     35 hostname itself. For example, "ample.com" would match ample.com, ample.com:80,
     36 and www.ample.com, but not www.example.com or ample.com.org.
     37 
     38 Setting the *noproxy* string to "" (an empty string) explicitly enables the
     39 proxy for all hostnames, even if there is an environment variable set for it.
     40 
     41 Enter IPv6 numerical addresses in the list of hostnames without enclosing
     42 brackets:
     43 
     44     "example.com,::1,localhost"
     45 
     46 Since 7.86.0, IP addresses specified to this option can be provided using CIDR
     47 notation: an appended slash and number specifies the number of "network bits"
     48 out of the address to use in the comparison. For example "192.168.0.0/16"
     49 would match all addresses starting with "192.168".
     50 
     51 The application does not have to keep the string around after setting this
     52 option.
     53 
     54 Using this option multiple times makes the last set string override the
     55 previous ones. Set it to NULL to disable its use again.
     56 
     57 # Environment variables
     58 
     59 If there is an environment variable called **no_proxy** (or **NO_PROXY**),
     60 it is used if the CURLOPT_NOPROXY(3) option is not set. It works exactly
     61 the same way.
     62 
     63 # DEFAULT
     64 
     65 NULL

     74   CURL *curl = curl_easy_init();
     75   if(curl) {
     76     /* accept various URLs */
     77     curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
     78     /* use this proxy */
     79     curl_easy_setopt(curl, CURLOPT_PROXY, "http://proxy:80");
     80     /* ... but make sure this host name is not proxied */
     81     curl_easy_setopt(curl, CURLOPT_NOPROXY, "www.example.com");
     82     curl_easy_perform(curl);
     83   }
     84 }
