17# NAME
18
19CURLOPT_PATH_AS_IS - do not handle dot-dot sequences
20
21# SYNOPSIS
22
23~~~c
24#include <curl/curl.h>
25
26CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PATH_AS_IS, long leaveit);
27~~~
28
29# DESCRIPTION
30
31Set the long *leaveit* to 1, to explicitly tell libcurl to not alter the
32given path before passing it on to the server.
33
34This instructs libcurl to NOT squash sequences of "/../" or "/./" that may
35exist in the URL's path part and that is supposed to be removed according to
36RFC 3986 section 5.2.4.
37
38Some server implementations are known to (erroneously) require the dot-dot
39sequences to remain in the path and some clients want to pass these on in
40order to try out server implementations.
41
42By default libcurl normalizes such sequences before using the path.
43
44The corresponding flag for the curl_url_set(3) function is called
45**CURLU_PATH_AS_IS**.
