CURLOPT_IGNORE_CONTENT_LENGTH(3) Introduction to Library Functions

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 doing HTTP transfers with ancient web servers
which report incorrect content length for files over 2 gigabytes. If
this option is used, curl cannot accurately report progress, and it
instead stops 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 unconditionally causes
libcurl to report error.

Only use this option if strictly necessary.

DEFAULT

PROTOCOLS

EXAMPLE

curl_easy_setopt(curl, CURLOPT_IGNORE_CONTENT_LENGTH, 1L);

curl_easy_perform(curl);
}
}
