Since this option is also used for FTP, it needs to work to set for applications even if hyper doesn't support it for HTTP. Verified by test 1137. Updated docs to specify that the option doesn't work for HTTP when using the hyper backend. Closes #7614

.TH CURLOPT_IGNORE_CONTENT_LENGTH 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.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 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.
|
|
.SH "SEE ALSO"
