GZIP not working for JS or CSS

[Blair]

Running v4.0.17 I can't get gzip to work with JS or CSS mime types.

I've followed the recommendations in this support topic: ../support/forum/showthread.php?p=19488

And appear to have the same issue as this topic: ../support/forum/showthread.php?t=4130

Sorry, can't post complete links. Isn't this a customer forum? The links are within this forum.

OS is CENTOS 5.5 x86_64

I seem to have run up against a wall. Any recommendations welcome.

check your site with firebug -> Net, what the "Content-Type" of the css and js ?

 

[Blair]

Firebug shows the following:

JS

Content-Type application/javascript

CSS

Content-Type text/css

If js and css are generated dynamically by PHP, you need to enable compression for dynamic content.

using firebug checked the website, css and js are compressed

please note "Content-Encoding: gzip"
it tells the file is GZIP'ed.
