+# NAME
+
+CURLOPT_REQUEST_TARGET - alternative target for this request
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_REQUEST_TARGET, string);
+~~~
+
+# DESCRIPTION
+
+Pass a char pointer to string which libcurl uses in the upcoming request
+instead of the path as extracted from the URL.
+
+libcurl passes on the verbatim string in its request without any filter or
+other safe guards. That includes white space and control characters.
+
+Using this option multiple times makes the last set string override the
+previous ones. Set it to NULL to disable its use again.
+
+The application does not have to keep the string around after setting this
+option.
+
+# DEFAULT
+
+NULL
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/*");
+    curl_easy_setopt(curl, CURLOPT_CUSTOMREQUEST, "OPTIONS");
+
+    /* issue an OPTIONS * request (no leading slash) */
+    curl_easy_setopt(curl, CURLOPT_REQUEST_TARGET, "*");
+
+    /* Perform the request */
+    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).
