My friend Rodolfo Finochietti has modified the WSE2 WS-Compression filter based on the Plumbwork Orange version.
New features in this filter:
1. Compress attachments
2. More algorithms (Deflate, Zip)
3. Compression level (set through compression context)
4. Threshold. Compresses according to the minimum message size (body size plus all attachmnets size)
5. Several other improvements and code cleaning.
