We received a request from our client that they want every form on their site to store certain fields in a cookie, so that every time after the first submit, the form would be filled in with data from the cookie.
We created an actionfilter attribute to use on the methods that required this functionality. The idea would be to store the data of the FormCollection in the cookie, and every time the action gets called, we would check if the cookie exists and update the value accordingly.
The problem, is that the Form is read only, and cannot be modified. How would I achieve this functionality.
