Gzip encoding is optional in most java servlet containers, as it is
implemented by a Filter that the application must configure.    I've
never heard of an application not working with a client because it did
not have compression configured.

accept connections with deflate-stream, or is it only mandatory that
they request that extension, but can accept connections without
