Summary
server-set cookie aborts cookie jar load
Details

When 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.
