I have a structure that groups a number of fields together that I want to use to retain values between different web pages. My plan was to transfer the structure to a session variable and retrieve it as each page loads. In theory each of the different fields could be stored in and retrieved from separate session variables but the structure approach seemed more elegant.
I was initially assuming I would be a "sensible time" (e.g. specific event) when I could consistently save the structure content to the session variable but I realise that I may be on the wrong track and that it may be necessary to transfer to the session variable to the structure each time one of the individual field values is updated as there is no way of determining when the user is about to move to another page.
Is there a solution to this or a better approach?
