Why does gzipped html file display without JS and CSS?

When serving JavaScript files, is it safe to gzip it by default

I run an ASP.NET application on IIS 6.0. Usually I have compression turned on for both dynamic and static files.

What are the different zlib compression methods and how do I force the default in Java's Deflater?

I am using DeflaterOutputStream to compress data as a part of a proprietary archive file format. I'm then using jcraft zlib code to decompress that data on the other end.
