BTW, I think compression should be part of the HTTP connector. Every modern 
browser out there sends accept-encoding headers with the appropriate value :
- IE 5 sends : gzip, deflate
- Mozilla sends : gzip,deflate,compress,identity
- Netscape 4.7 sends : gzip
So roughly 95% of the requests will be wrapped by a compression valve. I also 
think that compression should be considered basic functionality.

Makes a lot of sense.
