in regard to limitation of number of cookies, here's the HTTP spec:
there are limitations on the number of cookies that a client can store at
any one time. this is a specification of the minimum number of cookies
that a client should be prepared to receive and store:
* 300 total cookies
* 4 kilobytes per cookie, where the name and the OPAQUE_STRING combine to
form the 4 kilobte limit.
* 20 cookies per server or domain. (note that completely specified hosts
and domains are treated as separate entities and have a 20 cookie
limitation for each, not combined.)
servers should not expect clients to be able to exceed these limits. when
the 300 cookie limit or the 20 cookie per server limit is exceeded,
clients should delete the least recently used cookie. when a cookie
larger than 4 kilobytes is encountered the cookie should be trimmed to
fit, but the name should remain intact as long as it is less than 4
kilobytes.
hope this helps. :)
