I am very new to Asp.net MVC and still learning. I have been developing a portal type website to display database data. In development and testing on my local computer I was very enthusiastic about the fact that when re-routing to a new page (all pages use _layout as header section) that there was NOT a total page repaint. However, I have just recently published to live Website and have noticed that on each reroute to new page that it is re-painting everything including the _layout header section. Am I missing something? I thought that was one of the advantages to MVC. All of my redirections are either @html.actionlink or @url.action with appropriate "controller" and "action" calls. Again, everything works awesome in test on development computer but when live on website, I get total page re-paints. Any insight appreciated!
