.TH CURLOPT_IGNORE_CONTENT_LENGTH 3 "19 Jun 2014" libcurl libcurl
.SH NAME
CURLOPT_IGNORE_CONTENT_LENGTH \- ignore content length
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_IGNORE_CONTENT_LENGTH,
                          long ignore);
.SH DESCRIPTION
If \fIignore\fP 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.
.SH DEFAULT
0
.SH PROTOCOLS
HTTP
.SH EXAMPLE
.nf
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);
}
.fi
.SH 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.
.SH RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
