# NAME
|
||
|
|
|
||
|
|
CURLOPT_IGNORE_CONTENT_LENGTH - ignore content length
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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.

|
||
|
|
|

/* we know the server is silly, ignore content-length */
|
||
|

# 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.
