On labs, http headers do not have
Content-Encoding: gzip
when serving up legals-nightly. (Sample headers below.) If I
understand Henry correctly, this means we're not gzipping.
Here's some of our server.xml on labs which I think explains why
we're not gzipping. Sounds like we should turn on gzipping on tomcat
labs.

Instructions:
Restart the Tomcat, and then you can see if it is working by clearing
the browser cache, and
loading the demo dhtml app. In LiveHTTPHeaders in Firefox you should
see headers like this

When documenting this, we need to discuss, right up front, the
importance of having gzip compression switched on for the HTTP
server. There is an enormous size difference between compressed and
uncompressed, and this isn't an issue for SWF, which has internal
gzip compression.
When serving from LPS, the Javascript should be automatically
gzipped. It is, right?
