CURLOPT_PATH_AS_IS - do not handle dot dot sequences
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PATH_AS_IS, long leaveit);
Set the long leaveit to 1, to explicitly tell libcurl to not alter the
given path before passing it on to the server.
This instructs libcurl to NOT squash sequences of "/../" or "/./" that
may exist in the URL's path part and that is supposed to be removed
according to RFC 3986 section 5.2.4.
Some server implementations are known to (erroneously) require the dot
dot sequences to remain in the path and some clients want to pass these
on in order to try out server implementations.
By default libcurl will merge such sequences before using the path.
CURL *curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/../../etc/password");
curl_easy_setopt(curl, CURLOPT_PATH_AS_IS, 1L);
