Practical user agent implementations have limits on the number and
size of cookies that they can store. In general, user agents' cookie
support should have no fixed limits. They should strive to store as
many frequently-used cookies as possible. Furthermore, general-use
user agents SHOULD provide each of the following minimum capabilities
individually, although not necessarily simultaneously:

* at least 300 cookies

* at least 4096 bytes per cookie (as measured by the characters
that comprise the cookie non-terminal in the syntax description
of the Set-Cookie2 header, and as received in the Set-Cookie2
header)

* at least 20 cookies per unique host or domain name

User agents created for specific purposes or for limited-capacity
devices SHOULD provide at least 20 cookies of 4096 bytes, to ensure
that the user can interact with a session-based origin server.
