How do I issue a cookie to a client?
How do I store the cookie on the client? Does it need to be explicitly passed to the web service with each method call, by my code?
How do I store a single data value from a client on the server, and later update it for that same client?
Where does it get stored within the application? How do I access data for all the clients in order to, lets say, calculate the average of all data values provided by all the clients that have accessed the service so far?
Thanks for your help! (any code or links much appreciated too)
