SLTCViewState
If you've done any serious work with .NET based webpages, then you're aware of the ViewState technique for dealing with maintaining page settings during postbacks. This tends to put a lot of stress on internet connectivity by passing a lot of data back and forth between the browser and the server.
With SLTCViewState, we've developed a way around it that allows you to continue to work with ViewState, while reducing the amount of data sent between the browser and your servers. In particular on pages with large amounts of data, the savings to both your throughput and the time it takes your user to download the page can be significant, resulting in a faster, smoother web browsing experience.
This is included with our SanLuisTech library.
