#name: livecruncher v1.0
#function: html-code is compressed by php4 and recompressed by javascript
#advantage: up to 25% less traffic, thus more speed, less costs
#files can also be stored in the crunched version
#recrunch - javascript is very fast.
#how it works:
# html is splitted by "<" and stored in an array (unique).
# then html is parsed. each word is replaced by it's index.
# if you crunch only text, crunchfactor will be only 1%, the more text the better.
# html works pretty good.
