I don't use this feature, it just puts extra work on the server and client to save something. If service providers think it is necessary to save bandwidth, they could probably compress the content themselves. But from looking at the code, you shouldn't have to do anything except configure the module to get transparent compression. You have to set minimum file content size, etc. and adp needs independent configuration if you use adps. In other words, you don't have to edit your site code to get compression with ns_zlib.
