[Cosmo-dev] Gzipping dojo.js

[Jared Rhine]

Props to everyone for the cool single-file compacted dojo.js.  It's 
about 444Kb.

I just filed an enhancement, #8071, to capture an idea about dropping 
another 75% off of that.  The body of that ticket:

---

The compiled dojo.js added in 0.6.0 is 444Kb.  When gzipped (with 
regular compression), the size is 114Kb.

One way to achieve gzipping would be with mod_deflate (which works). 
However, since this resource is static, an even more clever solution 
would be to statically gzip the resulting file, during build, and 
configure Tomcat to serve the dojo.js.gz version when an Accept-Encoding 
of gzip is received.  (So both dojo.js and dojo.js.gz would be found 
on-disk).  In Apache, this would be simple (MultiViews and related 
options).  In Tomcat, I don't know the procedure.

This approach would get all the benefits of a remarkably compact dojo.js 
(114K!) for no additional server CPU overhead.

---

I have mod_deflate working on lab.osaf.us, so we do have access to this 
114Kb version already.  Doing that statically though, and have that work 
out of the box with snarf, would absolutely rock.  No need to target for 
any particular Cosmo release; it's just an idea filed into bugzilla for 
reference.
