This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
The problem I am having is when a user enters the values into the form and submits it. If any one of the user inputted values are invalid, then I get the action to forwards back to the input page. In doing so all the values that the user inputed in the form are lost. Is there any way in which these values can be stored, apart from cookies.
