john, rmd,
You can use this using your uploader tools. I use the free Cloudberry which can do this easily (asked everytime you upload)

How do I perform step 4 from the section entitled Serving Static Compressed File from the Cloud.

4. Add one more Header only for compressed version (e.g:style.gz.css) with “Content-Encoding” and the value is “gzip”

How do you do this?

Very nice tutorial. Just a question for step 4, how can I set the content encoding of the compressed file into gzip?

I tried adding to functions.php it broke php. Can u add instructions on adding to functions.php because index.php is overwritten on every wordpress version upgrade installed.

thx

IE6 doesn't seem to send an HTTP_ACCEPT_ENCODING header.

if (isset($_SERVER['HTTP_ACCEPT_ENCODING']))
{
    if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip'))
     $GLOBAL_GZSTRING=".gz"; 
    else
     $GLOBAL_GZSTRING=""; 
}
else
 $GLOBAL_GZSTRING="";

Thanks for the tip, this seems to be working for me. It’s a lot of work, but probably worth it since I have a lot of uncompressed scripts & CSS on CloudFront.

Just a suggestion: it’s probably better to add the line the functions.php of your theme instead of the WordPress index.php:

$GLOBAL_GZSTRING=””;
if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], ‘gzip’)) $GLOBAL_GZSTRING=”.gz”; else $GLOBAL_GZSTRING=””

Then, add at the top of header.php, and you can use it anywhere!

Thanks for the tip! Great explanation. I guess it may be obvious to many but I didn’t realize it was as easy as using 7zip on the file. Thanks again.
