Ok, I had to look this up...
<rfc 2901 6.3>
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 size
of the characters that comprise the cookie non-terminal in the
syntax description of the Set-Cookie header)
* at least 20 cookies per unique host or domain name
</rfc>
So a serialize string such as figuring most rss fees will have special
data in them:
$rss[]=http://www.google.com/search?q=asdf&sourceid=opera&num=0&ie=utf-8&oe=utf-8
yields 92 bytes, leaving you have around 40(max) different feeds stored on
the client. Minus any other cookies you may want to store. Now even if
that doesn't discurage you from using cookies.
<rfc 2901 6.3 last sentence>
Applications should use as few and as small cookies as possible, and
they should cope gracefully with the loss of a cookie.
</rfc>
HTH,
Curt
