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 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".

The application does not have to keep the string around after setting this option.
