Several content transformation proxies and the Internet in general includes forward caches. Current definition of HTTP includes indication of transformation using Vary header. In most cases the Content Transformation proxies and servers vary their responses based on User-Agent header. The number of User-Agent string in is very high and caches cannot possibly store these mean copies of the response. Most servers are likely to classify the devices in certain meta-groups for the purpose of content transformation. However, this meta-group is expected to be server specific. In absence of formal method, the caches will be left to guess the meta-group. What will be the method to solve this?
