DescriptionWhen writing a long cookie name and value to a Netscape cookie jar, a remote HTTP server can make `curl` write a record that exceeds its line-length parsing limit. Consequently, any subsequent `curl` invocation reading from that same cookie jar using `--cookie` silently aborts parsing prematurely upon encountering the too long line, ignoring all subsequent valid cookies in the file.
