- public class TEFilter
- extends ResourceFilter
This filter will compress the content of replies using GZIP or whatever
encoding scheme requested in the TE: header of the request.
Compression is done on the fly. This assumes that you're really
on a slow link, where you have lots of CPU, but not much bandwidth.
A nifty usage for that filter, is to plug it on top of a
org.w3c.jigsaw.proxy.ProxyFrame
, in which case it
will encode the data when it flies out of the proxy.
