| .TH CURLOPT_IGNORE_CONTENT_LENGTH 3 "June 03, 2021" "libcurl 7.78.0" "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 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 the hyper backend. |
| .SH RETURN VALUE |
| Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. |
| .SH "SEE ALSO" |
| .BR CURLOPT_HTTP_VERSION "(3), " CURLOPT_MAXFILESIZE_LARGE "(3), " |
