+# NAME
+
+CURLOPT_NOPROXY - disable proxy use for specific hosts
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOPROXY, char *noproxy);
+~~~
+
+# DESCRIPTION
+
+Pass a pointer to a null-terminated string. The string consists of a comma
+separated list of hostnames 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, "ample.com" would match ample.com, ample.com:80,
+and www.ample.com, but not www.example.com or ample.com.org.
+
+Setting the *noproxy* string to "" (an empty string) explicitly enables the
+proxy for all hostnames, even if there is an environment variable set for it.
+
+Enter IPv6 numerical addresses in the list of hostnames without enclosing
+brackets:
+
+    "example.com,::1,localhost"
+
+Since 7.86.0, IP addresses specified to this option can be provided using CIDR
+notation: an appended slash and number specifies the number of "network bits"
+out of the address to use in the comparison. For example "192.168.0.0/16"
+would match all addresses starting with "192.168".
+
+The application does not have to keep the string around after setting this
+option.
+
+Using this option multiple times makes the last set string override the
+previous ones. Set it to NULL to disable its use again.
+
+# Environment variables
+
+If there is an environment variable called **no_proxy** (or **NO_PROXY**),
+it is used if the CURLOPT_NOPROXY(3) option is not set. It works exactly
+the same way.
+
+# DEFAULT
+
+NULL

+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    /* accept various URLs */
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
+    /* 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);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
