Startup Idea : Cache Timeout Read-in

The statelessness of HTTP means that data is requested multiple times in order to fulful a request. For example, a multiple page form will typically involve queries to return the logged in user, the state of the form and the fields that have been completed. This data loaded by a web server in a controller may be useful across multiple requests. Memory caches keep data from expensive requests in memory until the next request. These caches need to be explicitly requested for the data to come available. A predictive cache read would associate a timeout with each HTTP request for when the data should be re-loaded into memory. When a user submits a form there will be a predictable delay until the next request. This lump of data - potentially representing the output of many queries - can then be associated with the user HTTP request. This data will only be read back into memory when the time delay elapses as a way of preempting the user’s next request.
