I just wanted to point out (even though apache in Debian hasn't been updated for quite while) that there is newer version of mod_gzip available.
>From http://www.RemoteCommunications.com/apache/mod_gzip/ : mod_gzip v 1.3.19.1a - 03/08/01 that can compress both STATIC and DYNAMIC output for both external CGI and 'mod_xxxx' Apache module output is now available. Other features include better SSI (Server Side Include) compression support, complete Location, Directory and Virtual Host support, and new 'Dechunking' option which can now compress responses that are already being generated using Transfer-encoding. Apparently, it has been updated to the latest version of Apache, v1.3.19. Other change in the changes.txt file: http://www.RemoteCommunications.com/apache/mod_gzip/src/1.3.19.1a/changes.txt - Peter.
