Subject Re: Compression on client side vs server side
Date Mon, 02 Apr 2012 15:54:10 GMT

how do you select between client- and serverside compression? i'm using 
hector and i set compression when creating a cf, so the compression 
executes when inserting the data "on the server" oO

greetings, martin
