A possible compression scheme

[Brad Clements]

I think this would be a good idea too, however consider also that the 
client may have limited memory capacity and needs some way to tell 
the server what the cache size is.

We must come down from our heights, and leave our straight 
paths, for the byways and low places of life, if we would 
learn truths by strong contrasts; and in hovels, in forecastles, 
and among our own outcasts in foreign lands, see what has been 
wrought upon our fellow-creatures by accident, hardship, or vice.
