CURLOPT_PATH_AS_IS(3) Introduction to Library Functions

NAME

CURLOPT_PATH_AS_IS - do not handle dot-dot sequences

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PATH_AS_IS, long leaveit);

DESCRIPTION

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 normalizes such sequences before using the path.

This is a request for the first request libcurl issues. When
following redirects, it may no longer apply.

The corresponding flag for the curl_url_set(3) function is called
CURLU_PATH_AS_IS.

DEFAULT
