If you use a shared host as I do, you may have a hard time getting this version to work. I spent days on it, before I worked out another method that works.

If your host has the php and the zlib extension you can compress your css and javascript files using an alternate method explained below.

It can also merge your files and cache them which will make your site load much faster again!

Hope this helps!

Man does mod_rewrite have bugs in it or what. I’ve been looking on the web and it appears to have loads. That line:
RewriteCond %{HTTP_USER_AGENT} “MSIE 7|Firefox”

…it just goes ahead and rewrites anyway regrdless of whether it matches the user agent string or not. I’ve verified this with multiple browsers and also Rex Swain HTTP viewer (http://www.rexswain.com/httpview.html). I’ve tried it in every configuration possible - it just wants to do it’s own thing.

(with FilesMatch tags around the code a la post 15)

I use…

ForceType text/javascript
Header set Content-Encoding: gzip

RewriteCond %{HTTP_USER_AGENT} “MSIE 7|Firefox”
RewriteCond %{REQUEST_FILENAME}.gz -f
RewriteCond %{HTTP:Accept-Encoding} gzip
RewriteRule (.*)\.js$ $1.js.gz [QSA,L]
ForceType text/javascript

… but it only works if the original javascript file DOESNT exist. If it does, it uses that instead. This happens on both ie7 and firefox. I don’t know why this happens but it makes it impossible to use becuase browsers other than ie7 and firefox dont support it or have bugs, and ie7 and ifrefox just use the regular file anyway. Maybe there’s something wrong with the code…

[...] For more information about this gzip-encoding configuration, please google “IE gzip javascript encoding” or read Joshua Eichorn’s blog article “Compressing JavaScript and CSS”. [...]

Ugh! The tags were eaten by your script. My last post should read:

[FilesMatch "\.js.gz$"]
ForceType text/javascript
Header set Content-Encoding: gzip
[/FilesMatch]
[FilesMatch "\.js$"]
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} !”.*Safari.*”
RewriteCond %{HTTP_ACCEPT} >gzip
RewriteCond %{REQUEST_FILENAME}.gz -f
RewriteRule ^(.+).js$ $1.js.gz [QSA,L]
ForceType text/javascript
[/FilesMatch]

Change [ & ] to angle braces.

The problem of setting the Content-Encoding piqued my curiosity so looked around a bit and found this page:
http://zuble.blogspot.com/2007/02/compressed-js-and-modrewrite.html

I made a couple of changes to his version:

ForceType text/javascript
Header set Content-Encoding: gzip

RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} !”.*Safari.*”
RewriteCond %{HTTP_ACCEPT} >gzip
RewriteCond %{REQUEST_FILENAME}.gz -f
RewriteRule ^(.+).js$ $1.js.gz [QSA,L]
ForceType text/javascript

Works for me.

You can view and analyze HTTP headers and HTTP content with SoftX HTTP Debugger.
