Abstract a key/value pair, which has some 2109 attributes. Morsels are dictionary-like objects, whose set of keys is constant --- the valid 2109 attributes, which are The attribute httponly specifies that the cookie is only transferred in HTTP requests, and is not accessible through JavaScript. This is intended to mitigate some forms of cross-site scripting. The attribute samesite controls when the browser sends the cookie with cross-site requests. This helps to mitigate CSRF attacks. Valid values are "Strict" (only sent with same-site requests), "Lax" (sent with same-site requests and top-level navigations), and "None" (sent with same-site and cross-site requests). When using "None", the "secure" attribute must also be set, as required by modern browsers. The attribute partitioned indicates to user agents that these cross-site cookies should only be available in the same top-level context that the cookie was first set in. For this to be accepted by the user agent, you must also set Secure. In addition, it is recommended to use the Host prefix when setting partitioned cookies to make them bound to the hostname and not the registrable domain. Read CHIPS (Cookies Having Independent Partitioned State)_ for full details and examples. The keys are case-insensitive and their default value is ''. The encoded value of the cookie --- this is what should be sent. Set the key, value and coded_value attributes. Whether K is a member of the set of keys of a Morsel. Return a string representation of the Morsel, suitable to be sent as an HTTP header. By default, all the attributes are included, unless attrs is given, in which case it should be a list of attributes to use. header is by default "Set-Cookie:". Return an embeddable JavaScript snippet, which, if run on a browser which supports JavaScript, will act the same as if the HTTP header was sent. The meaning for attrs is the same as in output. Return a string representing the Morsel, without any surrounding HTTP or JavaScript. The meaning for attrs is the same as in output. Update the values in the Morsel dictionary with the values in the dictionary values. Raise an error if any of the keys in the values dict is not a valid 2109 attribute. Return a shallow copy of the Morsel object. Raise an error if key is not a valid 2109 attribute, otherwise behave the same as dict.setdefault.
