Hi Victor, I'm not sure if this is any use to you, but this guy seemed to have the same issue as you: http://stackoverflow.com/questions/1061066/http-compression-how-to-send-precompressed-files-that-exist-in-a-ear-file
Are you able to use the suggestion of an output filter to add the content-encoding header for your already compressed files? It should work if you can classify your precompressed files somehow - e.g. existing in a directory or following a certain filename convention. Hope that helps
