12 *noproxy);

15 Pass a pointer to a zero terminated string. The string consists of a
16 comma separated list of host names that do not require a proxy to get
17 reached, even if one is specified. The only wildcard available is a
18 single * character, which matches all hosts, and effectively disables
19 the proxy. Each name in this list is matched as either a domain which
20 contains the hostname, or the hostname itself. For example, example.com
21 would match example.com, example.com:80, and www.example.com, but not
22 www.notanexample.com or example.com.othertld.
23
24 If the name in the noproxy list has a leading period, it is a domain
25 match against the provided host name. This way ".example.com" will
26 switch off proxy use for both "www.example.com" as well as for
27 "foo.example.com".
28
29 Setting the noproxy string to "" (an empty string) will explicitly
30 enable the proxy for all host names, even if there is an environment
31 variable set for it.
32
33 Enter IPv6 numerical addresses in the list of host names without
34 enclosing brackets:
35
36 "example.com,::1,localhost"
37
38 The application does not have to keep the string around after setting
39 this option.
40
42 If there's an environment variable called no_proxy (or NO_PROXY), it
43 will be used if the CURLOPT_NOPROXY(3) option is not set. It works
44 exactly the same way.
