We are getting off the topic, but, hey. I don't think that would work
very well, mostly because most html (and probably vrml) documents change
quite often. I sometimes update mine several times in a day. If my
server which was caching documents had to query the cached documents
every time to see if they had changed, I don't think that there would be
a great increase overall in speed. This makes more sense with caching
images and sounds which can take a long time to download.
