I'm thinking about adding the functionality to auto save the user's data using ajax calls after each time he leaves a field and has changed the data in it, but my concern is about the amount of traffic and calls this will generate between the browser and the web server. Should I be concerned about this type thing of this in this day and age?
Overall, there aren't many fields - less than 50, but I can end up with multiple rows of data within it, ex a list of names with their related address, street, province/state, etc Besides the obvious point of the user never losing any of his data due to session timeout or network issues, another reason for me wanting to do this is because the data entered in certain fields can affect other fields, and generate errors and warnings that the user must address, so I'm thinking this would be a nice way of 'instant notification' of issues with the data Anybody have any thoughts?
