14# NAME
15
16CURLOPT_PATH_AS_IS - do not handle dot dot sequences
17
18# SYNOPSIS
19
20~~~c
21#include <curl/curl.h>
22
23CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PATH_AS_IS, long leaveit);
24~~~
25
26# DESCRIPTION
27
28Set the long *leaveit* to 1, to explicitly tell libcurl to not alter the
29given path before passing it on to the server.
30
31This instructs libcurl to NOT squash sequences of "/../" or "/./" that may
32exist in the URL's path part and that is supposed to be removed according to
33RFC 3986 section 5.2.4.
34
35Some server implementations are known to (erroneously) require the dot dot
36sequences to remain in the path and some clients want to pass these on in
37order to try out server implementations.
38
39By default libcurl normalizes such sequences before using the path.
40
41The corresponding flag for the curl_url_set(3) function is called
42**CURLU_PATH_AS_IS**.
