I'll list some off the top of my head:

 o one-time password/securID type authentication where a cookie is
   issued and considered as valid credentials for a certain period of
   time and then expired

 o other access control data, e.g. ACL's

 o being able to track usage patterns without forcing user

 o being able to customize the view through the proxy

 o maintaining client state on proxy side that useful and necessary,

	o to guarantee that a Java originated connection gets to the
	  same IP address as the Java applet was loaded from (to
	  avoid the DNS spoofing attack)

	o to guarantee the same proxy route to the origin server, to
	  avoid problems where sites would associate a client cookie
	  with the incoming IP address, and with multiple different
	  proxy routes end up in a situation where client's cookie is
	  considered invalid by the origin server because it came
	  through a different proxy route (different source IP

The two last subitems I don't mind if HTTP WG proposes some other
mechanism to deal with them; however, if we go with Proxy-cookies
(which I fully support), this would be a possible solution.
