-client to hold and then the client sends back those the server on subsequent
-requests to the same domains/paths for which the cookies were set.
+HTTP Cookies
-Cookies are either "session cookies" which typically are forgotten when the
-session is over which is often translated to equal when browser quits, or the
-cookies aren't session cookies they have expiration dates after which the
-client will throw them away.

-Netscape once created a file format for storing cookies on disk so that they
-would survive browser restarts. curl adopted that file format to allow sharing
-the cookies with browsers, only to see browsers move away from that
-format. Modern browsers no longer use it, while curl still does.
+ Cookies are set to the client with the Set-Cookie: header and are sent to
+ servers with the Cookie: header.
-The cookie file format stores one cookie per physical line in the file with a
-bunch of associated meta data, each field separated with TAB. That file is
-called the cookiejar in curl terminology.
