Abstract
Managing state information across communication sessions between a client and a server via a stateless protocol. The server delivers to the client a cacheable web page with a hyperlink to non-cacheable embedded content. In the hyperlink to the non-cacheable embedded content, the server adds a token or an identifier uniquely associated with the user. When the user obtains embedded content from the cached web page via the hyperlink, the identifier is also sent to the server. Upon receipt of the identifier from the client, the server accesses the stored state information. In this manner, the server manages state information related to the client across communication sessions without the use of cookies as long as the client caches the web page with the unique identifier.
