Summary: Unable to access site without an (unused!) --cookie-jar

Initial Comment:
curl 7.21.4 (universal-apple-darwin11.0) libcurl/7.21.4 OpenSSL/0.9.8r zlib/1.2.5
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smtp smtps telnet tftp
Features: AsynchDNS GSS-Negotiate IPv6 Largefile NTLM SSL libz

(that's stock curl from Mac OS X 10.7.1 "Lion")

I'm using curl to log into a site via an HTTP form, following subsequent redirects. If I pass "--cookie-jar -" and effectively ignore the stored cookie, everything works as hoped. If I don't, it doesn't. I tried both ways using --trace-ascii. WITHOUT a jar, I have a series of "Set-Cookie" results, followed by a site warning that my browser doesn't accept cookies. WITH a jar, I have a similar series of Set-Cookies except there is a "== Info: Added cookie" or "== Info: Replaced cookie" in-between them.

Since I'm not actually doing anything with the cookies dumped to stdout, the best guess I have is that "--cookie-jar" also enables the acceptance or use of cookies itself in curl. If this is the case, I think the documentation and guides could be updated to reflect that. If not, what explains this behavior?

Message:
This is not a bug, this is intentional.

curl doesn't activate "the cookie engine" unless you tell it to. One way
to tell it is by providing a cookie jar, another way is to use the
-b/--cookie option and provide a (non-existintg?) file to read cookies
from.

Do you have any suggested wording you think we should add to the "-c,
--cookie-jar" documentation to make this easier for a user to figure out?
