Question

I'm writing into a session cookie from my plugin in chrome. The browser seems to have a strict limit of 4kb for cookie size. It doesnt seem the case in firefox. Is there anyway i can increase the cookie size limit in chrome?

Thanks

According to RFC 1012 cookie size must not be limited by user agent. But the minimum capabilities of a browser or user agent should be at least 4096 bytes per cookie. This limit is applied to the name=value portion of the cookie only.

So some browsers can support longer cookies as well. List :

1. Internet Explorer 8 allowed cookies up to 4095 bytes
2. Chrome 9 allowed cookies up to 4096 bytes
3. Opera 11 allowed cookies up to 4096 bytes
4. Safari 5 allowed coookies up to 4097 bytes
5. Firefox 3.6.3 allowed cookies up to 4097 bytes

Chrome supports HTML5 localStorage that allows you to use a dictionary style look up. You can use this to store larger amounts of data instead of passing them back and forth using cookies.
