31 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_IGNORE_CONTENT_LENGTH,
34 If \fIignore\fP is set to 1L, ignore the Content-Length header in the HTTP
35 response and ignore asking for or relying on it for FTP transfers.
37 This is useful for HTTP with Apache 1.x (and similar servers) which will
38 report incorrect content length for files over 2 gigabytes. If this option is
39 used, curl will not be able to accurately report progress, and will simply
40 stop the download when the server ends the connection.
42 It is also useful with FTP when for example the file is growing while the
43 transfer is in progress which otherwise will unconditionally cause libcurl to
46 Only use this option if strictly necessary.
53 CURL *curl = curl_easy_init();

57 /* we know the server is silly, ignore content-length */
58 curl_easy_setopt(curl, CURLOPT_IGNORE_CONTENT_LENGTH, 1L);

64 Added in 7.14.1. Support for FTP added in 7.46.0.
66 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
