NAME

       CURLOPT_IGNORE_CONTENT_LENGTH - ignore content length

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_IGNORE_CONTENT_LENGTH,
                                 long ignore);

DESCRIPTION

       If  ignore  is set to 1L, ignore the Content-Length header in the HTTP response and ignore
       asking for or relying on it for FTP transfers.

       This is useful for HTTP with Apache 1.x (and similar servers) which will report  incorrect
       content  length  for files over 2 gigabytes. If this option is used, curl will not be able
       to accurately report progress, and will simply stop the download when the server ends  the
       connection.

       It  is  also useful with FTP when for example the file is growing while the transfer is in
       progress which otherwise will unconditionally cause libcurl to report error.

       Only use this option if strictly necessary.

DEFAULT

       0

PROTOCOLS

       HTTP

EXAMPLE

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

         /* we know the server is silly, ignore content-length */
         curl_easy_setopt(curl, CURLOPT_IGNORE_CONTENT_LENGTH, 1L);

         curl_easy_perform(curl);
       }

AVAILABILITY

       Added in 7.14.1. Support for FTP added in 7.46.0. This option is not working for HTTP when
       libcurl is built to use the hyper backend.

RETURN VALUE

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