Question

If cookie size is out of browser limit Will browsers throws some Error?

Answer 1

The browser just crashes !

Webpage becomes un-responsive and finally browser crashes, you can try this yourself :

1. Go to this website
2. Try setting a cookie with a very large size (a character repeated n number of times )
3. See for yourself

Highlights of the article shared above :

If you want to support most browsers, then don't exceed 50 cookies per domain, and don't exceed 4093 bytes per domain (i.e. total size of all cookies <= 4093 bytes)

Typically, the following are allowed:

• 300 cookies in total
• 4096 bytes per cookie
• 20 cookies per domain
• 81920 bytes per domain*

*Given 20 cookies of max size 4096 = 81920 bytes.
