Limits to Cookies
Typically a browser will restrict the number and size of cookies it will accept, e.g.:
- Maximum of 20 cookies per site,
- Maximum of 300 cookies total (from all sites),
- Maximum size of individual cookie is 4 kilobytes.
Users may of course configure their browsers to refuse all cookies, or only accept selected cookies.
Hence a Web application should not rely on cookies for basic functionality—only for “added value”.
