HTTP Cookies + +  1.1 Cookie overview + +  HTTP cookies are pieces of 'name=contents' snippets that a server tells the +  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. + +  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. + +  Cookies are set to the client with the Set-Cookie: header and are sent to +  servers with the Cookie: header. + +  For a very long time, the only spec explaining how to use cookies was the +  original Netscape spec from 1994: http://curl.haxx.se/rfc/cookie_spec.html + +  In 2011, RFC6265 (http://www.ietf.org/rfc/rfc6265.txt) was finally published +  and details how cookies work within HTTP. + +  1.2 Cookies saved to disk + +  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. + +  The netscape 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. + +  When libcurl saves a cookiejar, it creates a file header of its own in which +  there is a URL mention that will link to the web version of this document. + +  1.3 Cookies with curl the command line tool + +  curl has a full cookie "engine" built in. If you just activate it, you can +  have curl receive and send cookies exactly as mandated in the specs. + +  Command line options: + +  -b, --cookie + +    tell curl a file to read cookies from and start the cookie engine, or if +    it isn't a file it will pass on the given string. -b name=var works and so +    does -b cookiefile. + +  -j, --junk-session-cookies + +    when used in combination with -b, it will skip all "session cookies" on +    load so as to appear to start a new cookie session. + +  -c, --cookie-jar + +    tell curl to start the cookie engine and write cookies to the given file +    after the request(s) + +  1.4 Cookies with libcurl + +  libcurl offers several ways to enable and interface the cookie engine. These +  options are the ones provided by the native API. libcurl bindings may offer +  access to them using other means. + +  CURLOPT_COOKIE + +    Is used when you want to specify the exact contents of a cookie header to +    send to the server. + +  CURLOPT_COOKIEFILE + +    Tell libcurl to activate the cookie engine, and to read the initial set of +    cookies from the given file. Read-only. + +  CURLOPT_COOKIEJAR + +    Tell libcurl to activate the cookie engine, and when the easy handle is +    closed save all known cookies to the given cookiejar file. Write-only. + +  CURLOPT_COOKIELIST + +    Provide detailed information about a single cookie to add to the internal +    storage of cookies. Pass in the cookie as a HTTP header with all the +    details set, or pass in a line from a netscape cookie file. This option +    can also be used to flush the cookies etc. +     +  CURLINFO_COOKIELIST + +    Extract cookie information from the internal cookie storage as a linked +    list. + +  1.5 Cookies with javascript + +  These days a lot of the web is built up by javascript. The webbrowser loads +  complete programs that render the page you see. These javascript programs +  can also set and access cookies. + +  Since curl and libcurl are plain HTTP clients without any knowledge of or +  capability to handle javascript, such cookies will not be detected or used. + +  Often, if you want to mimic what a browser does on such web sites, you can +  record web browser HTTP traffic when using such a site and then repeat the +  cookie operations using curl or libcurl.  |
