Last month we've published an application optimization package -
Web Application Optimizer (WAO) - with features that include HTTP compression, ViewState optimization and CSS/Javascript optimization. WAO significantly increases the response time for Web applications of all sizes, and, most importantly, there is no need to modify the source code of your applications!
The package works in very different application scenarios and we've got plenty of useful feedback from the first group of users. There has been a slight confusion related to the availability of WAO in our MonoX framework. I wanted to formally announce that WAO is available by default in all versions of MonoX. It is easy to tell if the WAO is active by the absence of big ViewState data chunk from the page source.
