How to know apache server deflate/gzip compression is enabled

My Apache server admin claims that the server has deflate/gzip compression enabled.

But when I use some standard code for introducing deflate/gzip compression in my .htaccess file, it seems there is no compression in files.

I used the below lines in .htaccess

AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css
<FilesMatch "\\.(js|css|html|htm|php|xml)$">
  SetOutputFilter DEFLATE
</FilesMatch>

I am in doubt if the server really has enabled deflate/gzip compression. When I call phpinfo() it shows me the following rows related to deflate/gzip:

Stream Filter support           zlib.inflate, zlib.deflate
HTTP_ACCEPT_ENCODING            gzip, deflate
_SERVER["HTTP_ACCEPT_ENCODING"] gzip, deflate
_ENV["HTTP_ACCEPT_ENCODING"]    gzip, deflate

Do these lines show the server supports deflate/gzip compression or not?

And if not how should I understand?

After quite some search, it is possible to enable compression for PHP scripts by default by setting the PHP value zlib.compression_output = On. This way, PHP scripts behave always like if you would put ob_start("ob_gzhandler") manually.

For Apache it looks like you can only set it with SetOutputFilter.

`HTTP_ACCEPT_ENCODING gzip, deflate '`.

This line tells it all. It is configured.
