- make DEFAULT sections less repetitive

- make historic mentions use HISTORY

- generate the protocols section on `# %PROTOCOLS%` instead of guessing
  where to put it

- generate the availability section on `# %AVAILABILITY%` instead of
  guessing where to put it

- make the protocols section more verbose

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.

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

DEFAULT

%PROTOCOLS%

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL,
                     "https://example.com/../../etc/password");

    curl_easy_setopt(curl, CURLOPT_PATH_AS_IS, 1L);

    curl_easy_perform(curl);
  }
}

%AVAILABILITY%

RETURN VALUE

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
