Class representing an HTTP cookie.
In addition to its specific fields and methods, a Cookie instance is a delegator to the array of its values.
See RFC 2965.
Examples of use
cookie1 = CGI::Cookie.new("name", "value1", "value2", ...)
cookie1 = CGI::Cookie.new("name" => "name", "value" => "value")
cookie1 = CGI::Cookie.new('name' => 'name',
'value' => ['value1', 'value2', ...],
'path' => 'path', # optional
'domain' => 'domain', # optional
'expires' => Time.now, # optional
'secure' => true, # optional
'httponly' => true # optional
)
cgi.out("cookie" => [cookie1, cookie2]) { "string" }
name = cookie1.name
values = cookie1.value
path = cookie1.path
domain = cookie1.domain
expires = cookie1.expires
secure = cookie1.secure
httponly = cookie1.httponly
cookie1.name = 'name'
cookie1.value = ['value1', 'value2', ...]
cookie1.path = 'path'
cookie1.domain = 'domain'
cookie1.expires = Time.now + 30
cookie1.secure = true
cookie1.httponly = true
Name of this cookie, as a String
Path for which this cookie applies, as a String
Domain for which this cookie applies, as a String
True if this cookie is secure; false otherwise
True if this cookie is httponly; false otherwise

end
Create a new CGI::Cookie object.
name_string-
The name of the cookie; in this form, there is no
domainor expiration. Thepathis gleaned from theSCRIPT_NAMEenvironment variable, andsecureis false. *value-
value or list of values of the cookie
options_hash-
A
Hashof options to initialize thisCookie. Possible options are:- name
-
the name of the cookie. Required.
- value
-
the cookie’s value or list of values.
- path
-
the path for which this cookie applies. Defaults to the value of the
SCRIPT_NAMEenvironment variable. - domain
-
the domain for which this cookie applies.
- expires
-
the time at which this cookie expires, as a
Timeobject. - secure
-
whether this cookie is a secure cookie or not (default to false). Secure cookies are only transmitted to HTTPS servers.
- httponly
-
whether this cookie is a HttpOnly cookie or not (default to
false). HttpOnly cookies are not available to javascript.
These keywords correspond to attributes of the cookie object.

Parse a raw cookie string into a hash of cookie-name=>Cookie pairs.

end
@domain = str
end
Set domain for which this cookie applies

@httponly = !!val
end
# File tmp/rubies/ruby-3.0.5/lib/cgi/cookie.rb, line 202

"#<CGI::Cookie: #{self.to_s.inspect}>"
end
A summary of cookie string.

Set path for which this cookie applies

end
Convert the Cookie to its string representation.

end
Returns the value or list of values for this cookie.

replace(Array(val))
end
