Browser Cache & Gzip Compression

Hi,

I read in a W3 Total Cache support post:

Performance>Browser Cache uses Gzip compression. You need to make sure that mod_deflate is installed/enabled on your server so you can use Gzip compression.

My hosting server says:

To be able to use gzip, you have to activate the function in a .htaccess entry. To do this, edit the existing .htaccess file in the affected web space on your website. Now add the following code at the end of the file:

<IfModule mod_deflate.c>
<filesMatch “\.(js|css|html|php)$”>
SetOutputFilter DEFLATE
</filesMatch>
</IfModule>

I checked the .htaccess file on server and there is some code already added by W3 Total Cache regarding Browser Cache. It starts with # BEGIN W3TC Browser Cache.

Could you please let me know I still need to add the above code as suggested by the server, or is this is already included in this code added by W3 Total Cache. Is it save to paste this code here, is this a public forum? Do you need to see it to check?

Thanks
Mel
