Related to my JSP-4241 issue where I found Apache's mod_deflate to be a little flaky, I tried a different route and added this to JIRA's web.xml:

<filter-mapping>
<filter-name>gzip</filter-name>
<url-pattern>*.js</url-pattern>
</filter-mapping>

And JIRA is now compressing all the JS files that it sends which offers quite a bandwidth savings for my remote users considering the dashboard has about 123kb of javascript files.

I tried adding *.css but it isn't compressing those.

Can we have the *.js compression configured by default (assuming it passes your QA) (when gzip compression is turned on) and can we have *.css supported by the Filter as well?
