If we used Perl to do the compression, I think that would work quite well. However, I discovered a very odd bug in Netscape 4.x and compression.

For anyone not familar with this, most recent browsers are capable of receiving gzip compressed data, and they can uncompress it on the fly. The mod_gzip tilly mentioned is Apache's way of compressing data before the code crosses the wire. However, mod_gzip only compresses data if the browser passes certain headers to the webserver saying the browser is indeed capable of handling compression.

Netscape 4.x seems to be able to handle compressed HTML just fine. However, I've run into a problem where if you do something like this in your HTML code:
<script src="/lib/mylib.js">
The browser still sends the "compression okay" headers when requesting mylib.js, but it actually does not uncompress it properly once it has received the document. The actual error I received was a JavaScript error saying "invalid" this or that, but what it referred to was a block of binary looking data, which seems to be the uncompressed data received from the webserver. And mind you, it took me some time to figure out what in the world was going on, as I forgot I had gzip compression turned on ;-)

I discovered this using Apache 1.3.19, mod_gzip, and Netscape 4.77.
