I am learning as I go along, so please bear with me...

I just enable mod_deflate on our server last night. turned off gzip from admincp and added this to the end of our .htaccess file:
Code:
<ifmodule mod_deflate.c>
# Insert filter
SetOutputFilter DEFLATE
# Netscape 4.x has some problems...
BrowserMatch ^Mozilla/4 gzip-only-text/html
# Netscape 4.06-4.08 have some more problems
BrowserMatch ^Mozilla/4\.0[678] no-gzip
# MSIE masquerades as Netscape, but it is fine
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
# Don't compress images
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary
# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary
</ifmodule>
seems to be functioning correctly, but when I run Page Speed from Firebug, I get this (url's removed):
Compressing the following resources with gzip could reduce their transfer size by 44.2KiB (72% reduction).

  • Compressing /clientscript/vbulletin-core.js?v=403 could save 33.7KiB (73% reduction).
  • Compressing /clientscript/vbulletin_inlinemod.js?v=403 could save 3.8KiB (70% reduction).
  • Compressing /clientscript/vbulletin-ajax-threadlist.js?v=403 could save 3.6KiB (67% reduction).
  • Compressing /clientscript/vbulletin-sidebar.js?v=403 could save 3.2KiB (76% reduction).
why is the js not being compressed?

also, does it matter where the ifmodule mod_deflate.c instructions appear in the .htaccess file?

thanks for helping a noob!
