Cookies file format

-b cookies.txt

The cookies file format apparently consists of a line per cookie and each line consists of the following seven tab-delimited fields:

• domain - The domain that created AND that can read the variable.
• flag - A TRUE/FALSE value indicating if all machines within a given domain can access the variable. This value is set automatically by the browser, depending on the value you set for domain.
• path - The path within the domain that the variable is valid for.
• secure - A TRUE/FALSE value indicating if a secure connection with the domain is needed to access the variable.
• expiration - The UNIX time that the variable will expire on. UNIX time is defined as the number of seconds since Jan 1, 1970 00:00:00 GMT.
• name - The name of the variable.
• value - The value of the variable. From http://www.cookiecentral.com/faq/#3.5
