+# NAME
+
+CURLOPT_PROXYUSERPWD - username and password to use for proxy authentication
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYUSERPWD, char *userpwd);
+~~~
+
+# DESCRIPTION
+
+Pass a char pointer as parameter, which should be [username]:[password] to use
+for the connection to the HTTP proxy. Both the name and the password are URL
+decoded before used, so to include for example a colon in the username you
+should encode it as %3A. (This is different to how CURLOPT_USERPWD(3) is
+used - beware.)
+
+Use CURLOPT_PROXYAUTH(3) to specify the authentication method.
+
+The application does not have to keep the string around after setting this
+option.
+
+# DEFAULT
+
+This is NULL by default.
+
+# PROTOCOLS
+
+Used with all protocols that can use a proxy
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
+    curl_easy_setopt(curl, CURLOPT_PROXY, "http://localhost:8080");
+    curl_easy_setopt(curl, CURLOPT_PROXYUSERPWD, "clark%20kent:superman");
+    res = curl_easy_perform(curl);
+    curl_easy_cleanup(curl);
+  }
+}
+~~~
+
+# AVAILABILITY
+
+Always
+
+# RETURN VALUE
+
+Returns CURLE_OK if proxies are supported, CURLE_UNKNOWN_OPTION if not, or
+CURLE_OUT_OF_MEMORY if there was insufficient heap space.
