Just changed to an other web server.
At my old host, they refused to use the required modules,
so I had as an emergency solution:
RewriteCond %{HTTP:Accept-Encoding} !gzip
RewriteRule ^(.+\.($types))\$ [
$site_translated...] [R=307,L]
My new host told me, that he has the required modules and all goes automatic.
But as I checked with web-sniffer.net
I got back the same headers and length when I tested with
Accept-Encoding: gzip checked and unchecked
So I think there is something wrong and I have to add something to my .htaccess
My CMS compresses all htm and js files on my own computer and uploads to the server the compressed files.
AddEncoding gzip .js
AddEncoding gzip .htm
Is in my .htaccess
But what to do to deliver an the file inflated, when there is no accept enodicng gzip in the request?
