bionic (3) CURLOPT_NOPROXY.3.gz

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".

       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.

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