| .TH CURLOPT_NOPROXY 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options" |
| .SH NAME |
| CURLOPT_NOPROXY \- disable proxy use for specific hosts |
| .SH SYNOPSIS |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOPROXY, char *noproxy); |
| .SH DESCRIPTION |
| Pass a pointer to a zero 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" |
| |
| 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 |
| .nf |
| 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); |
| } |
| .fi |
| .SH AVAILABILITY |
| Added in 7.19.4 |
| .SH 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. |
