Highwinds has unveiled their Full Site Acceleration product. The main feature of the product is the ability to accelerate non-cacheable content.
This feature comes in addition to their existing capability to cache cacheable content close to the end user. Combining the two results in a powerful product capable of accelerating a full website where everything that can be cached is served from CDN nodes close to the end user while the retrieval of dynamic content like user specific data from the origin is accelerated, amongst others by using persistent connections to the origin.
