使用PHP在Bluemix中进行GZIP压缩

Question

Team,

I'm trying to enable GZIP compression in my bluemix php application, but it doesn't seem to work at all.

I've tried both options from this page: https://varvy.com/pagespeed/enable-compression.html and my application http://arkdev.mybluemix.net isn't enabling it. At least, I cannot see in the headers, neither GZIP compression test tools can see it.

This is my current code in htaccess:

RewriteEngine On
RewriteBase /
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*?)/?$ $1.php [NC,L]

# Enable GZIP
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
</ifmodule>
