| .TH CURLOPT_NOPROXY 3 "19 Jun 2014" libcurl libcurl |
| .SH NAME |
| CURLOPT_NOPROXY \- disable proxy use for specific hosts |
| .SH SYNOPSIS |
| .nf |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOPROXY, char *noproxy); |
| .fi |
| .SH 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 \fInoproxy\fP 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. |
| .SH "Environment variables" |
| If there's an environment variable called \fBno_proxy\fP (or \fBNO_PROXY\fP), |
| it will be used if the \fICURLOPT_NOPROXY(3)\fP option is not set. It works |
| exactly the same way. |
| .SH DEFAULT |
| NULL |
| .SH PROTOCOLS |
| Most |
| .SH 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); |
| } |
