Subject Re[4]: xml compressing
Date Wed, 05 Sep 2001 13:52:31 GMT
Hello java guru,

I want to compress the traffic and search any methods for do this.
It can be:
1. Using HTTP-Header and default browsers compression support.
2. Using browser plugins which do it and use autoinstall for upgrade
clients.
3. Anybody what you want...
I'm not spec in this area, but i'm not fool and know,
what i need client support of my compression methods.
xmlppm is a example of second way (if it really work as i think..).
On the other hand, i agree what server environment is that place where
this support should be tuned. I use Resin and try to ask to that.
I read what tomcat use this feature and i will try to do that also.
