doc-cookies

A little framework: a complete cookies reader/writer with full unicode support

Sometimes, cookies being formatted strings, it can be intricate to deal with them in a natural way. The following library aims to abstract the access to document.cookie by defining an object (docCookies) that is partially consistent with a Storage object. It offers also a full unicode support.

> Note: For never-expire-cookies we used the arbitrarily distant date Fri, 31 Dec 9999 23:59:59 GMT. If for any reason you are afraid of such a date, use the conventional date of end of the world Tue, 19 Jan 2038 03:14:07 GMT – which is the maximum number of seconds elapsed since since 1 January 1970 00:00:00 UTC expressible by a signed 32-bit integer (i.e.: 01111111111111111111111111111111, which is new Date(0x7fffffff 1e3)).*
