  .TH CURLOPT_NOPROXY 3 "November 04, 2020" "libcurl 7.77.0" "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 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, 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"
  
  IPv6 numerical addresses are compared as strings, so they will only match if
  the representations are the same: "::1" is the same as "::0:1" but they don't
  match.
  
  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.
