When compression is enabled in the server, an entry gets added to the obj.conf file. A sample entry is shown below:
Output fn=”insert-filter” filter=”http-compression” type=”text/*”
To restrict compression to documents of a particular type only, or to exclude browsers that don’t work well with compressed content, you would need to edit the obj.conf file. For more information on what you need to do to accomplish this, see the Sun Java System Web Server 6.1 SP12 NSAPI Programmer’s Guide.
