+# NAME
+
+CURLOPT_FRESH_CONNECT - force a new connection to be used
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FRESH_CONNECT, long fresh);
+~~~
+
+# DESCRIPTION
+
+Pass a long. Set to 1 to make the next transfer use a new (fresh) connection
+by force instead of trying to reuse an existing one. This option should be
+used with caution and only if you understand what it does as it may impact
+performance negatively.
+
+Related functionality is CURLOPT_FORBID_REUSE(3) which makes sure the
+connection is closed after use so that it cannot be reused.
+
+Set *fresh* to 0 to have libcurl attempt reusing an existing connection
+(default behavior).
+
+# DEFAULT
+
+0
+
+# %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_FRESH_CONNECT, 1L);
+    /* this transfer must use a new connection, not reuse an existing */
+    curl_easy_perform(curl);
+    curl_easy_cleanup(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).
