The page should not alter state, only display it. Don't store data required for long-running processes on the client.

When you generate the page, also generate the schedule that the SMS messages will be sent. Store these in a database on the server. Create a service that checks the database periodically for 'due' messages.

As responses come in, evaluate them and, if necessary, cancel any outstanding scheduled messages.

Use your client to poll responses from the server.

Cheers.
