        !            33: .SH DESCRIPTION
        !            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.
        !            36: 
        !            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.
        !            41: 
        !            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
        !            44: report error.
        !            45: 
        !            46: Only use this option if strictly necessary.
